Chairman’s Letter

Dear Shareholder,

During 2006, a year in which Vanguard 500 Index Fund marked its 30th anniversary, the fund returned 15.6% for Investor Shares and 15.7% for Admiral Shares. The fund outperformed the average return of its peers, and met its objective of closely tracking its unmanaged benchmark, the Standard & Poor’s 500 Index. Despite its strong return, the fund made no capital gains distributions, a benefit to shareholders in taxable accounts.

Shareholders who own the fund in a taxable account may wish to review the report on the fund’s after-tax returns on page 26.

On September 29, Vanguard introduced Signal Shares for the fund, which are available to certain qualifying institutional investors. Those shares returned 6.7% for the three months since their inception.

Strong second half pushed stocks to new high

Beginning in mid-July, stocks climbed steadily through the remainder of the year, with the Dow Jones Industrial Average setting a record high on December 27. For the year, the broad U.S. stock market gained 15.9%. Despite a soft housing sector and ongoing troubles within the U.S. auto industry, the economy continued to grow and corporate profits remained strong.

For the year, small-capitalization stocks beat out large-cap issues, and value stocks outperformed their growth-oriented counterparts. International stocks continued to best domestic equities, particularly in

2

emerging markets and Europe. A declining dollar further enhanced returns abroad for U.S.-based investors.

Bond returns remained modest as the Fed paused its rate hikes

The Federal Reserve Board extended its money-tightening campaign during the first half of the year, raising its target for the federal funds rate four times. The Fed then paused, leaving the target rate unchanged at 5.25% for the rest of the year, and inflation fears eased. Bond yields declined in the second half of the year, and short-term yields were higher than longer-term yields.

Fixed income returns for 2006 were modest, with the broad taxable bond market returning 4.3%, and municipal bonds providing 4.8%.

Fund benefited from advances across all industry groups

For Vanguard 500 Index Fund, and indeed the broader stock market, 2006 was a story in two parts. In the first half of the year, the benchmark S&P 500 Index posted a tepid 2.7% return, as jittery investors feared the economy was overheating. Inflation concerns then moderated in mid-summer, and the market gained momentum. A strong second half propelled the S&P 500 Index to a 15.8% 12-month return, which the 500 Index Fund closely tracked.

The index experienced broad-based gains, as all ten of its industry sectors recorded positive returns for the year. Through a combination of their strong returns and their weightings in the index, the financials, energy, and consumer discretionary

sectors were the largest contributors to the index’s overall result. Within the financials sector (which returned 19.1%), investment banks and brokerage firms were standouts, particularly in the final few months of the year. Energy stocks (up 24.2%) fluctuated during the period as did oil and gas prices, but delivered impressive returns for yet another year. Consumer discretionary stocks returned 18.8%, despite weakness in the homebuilding category, as several large media firms rebounded from underwhelming results in 2005.

Smaller sectors also packed a punch. Telecommunication services, utilities, and materials (whose weightings, if combined, would still rank as one of the index’s smallest sectors) all outperformed the index’s overall result. Investors in telecom stocks reacted favorably to consolidation in the sector, while electric, gas, and diversified utilities firms turned in impressive gains. In materials, chemical stocks did well, and the index’s steel companies rose an average of 80% during the 12 months.

Two of the economy’s less-flashy segments—industrials and consumer staples—posted solid double-digit returns that slightly trailed the index’s overall result. Meanwhile, information technology and health care, which returned 8.3% and 7.6%, respectively, were the laggards in 2006.

Fund has outperformed many of its actively managed peers

Over the past decade, the Investor Shares of the 500 Index Fund registered an average annual return of 8.3%, outpacing the average result of competing funds (most of which are actively managed) by 1.6 percentage points. Your fund’s superiority over its

competitors is the result of its lower operating and transaction costs and the fund’s full investment in the market without the drag of a cash holding—an enduring advantage. In addition, the fund nearly matched the return of its unmanaged benchmark, which has no costs or operating expenses.

Managing a portfolio that simply “owns the market” isn’t nearly as simple as it might sound. In seeking to track the returns of the S&P 500 Index, your fund’s advisor—Vanguard Quantitative Equity Group—must, in essence, hit a moving target every day that the stock market is open. By combining its collective experience and skill with sophisticated trading strategies, the Quantitative Equity Group has hit the mark consistently for more than three decades.

The group’s task is made easier by Vanguard’s low expenses. The 500 Index Fund is offered at a fraction of the cost of most of its peers. This allows for tighter tracking of the target index, and ultimately enables a greater portion of the fund’s returns to reach shareholders’ pockets.

Thirty years later, fund’s strategy remains simple, but powerful

In the 30 years since its inception, the case for Vanguard 500 Index Fund has grown stronger with every year of testing in the real-world laboratory of the financial markets. While the 500 Index Fund story remains the same—low costs, diversified exposure to 500 of the U.S. market’s largest stocks—the investment environment has changed substantially.

For example, the universe of mutual funds for investors to choose from has grown from several hundred in 1976 to many thousand today. Such an immense array of choices can make selecting the appropriate funds seem overwhelming for individual investors. In addition, today’s investors are barraged with much more “noise”—newspapers, magazines, cable networks, websites, and blogs—each happy to opine on which stocks and which funds will outperform the market. Amid all the chatter, “seeking to match the market’s return” does not make a good sound bite. Indexing isn’t a fancy investment strategy—perhaps it’s even a bit dull. But it has proven to be a smart and powerful approach. From its 1976 inception through December 31, 2006, the 500 Index Fund’s 12.2% average annual return has translated nearly all of the stock market’s gains into shareholder wealth.

After 30-plus years, we still believe the 500 Index Fund is a strong foundation for a balanced and diversified investment portfolio.

Thank you for investing with Vanguard.

Sincerely,

John J. Brennan

Chairman and Chief Executive Officer

Notes to Financial Statements

Vanguard 500 Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers three classes of shares: Investor Shares, Admiral Shares, and Signal Shares. Investor Shares are available to any investor who meets the fund’s minimum purchase requirements. Admiral Shares are designed for investors who meet certain administrative, servicing, tenure, and account-size criteria. Signal Shares are designed for institutional investors who meet certain administrative, servicing, and account-size criteria. Signal Shares were first issued on September 29, 2006.

A. The following significant accounting policies conform to generally accepted accounting principles for U.S. mutual funds. The fund consistently follows such policies in preparing its financial statements.

1. Security Valuation: Securities are valued as of the close of trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the valuation date. Equity securities are valued at the latest quoted sales prices or official closing prices taken from the primary market in which each security trades; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Securities for which market quotations are not readily available, or whose values have been materially affected by events occurring before the fund’s pricing time but after the close of the securities’ primary markets, are valued by methods deemed by the board of trustees to represent fair value. Investments in Vanguard Market Liquidity Fund are valued at that fund’s net asset value. Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value.

2. Futures Contracts: The fund uses index futures contracts to a limited extent, with the objectives of maintaining full exposure to the stock market, enhancing returns, maintaining liquidity, and minimizing transaction costs. The fund may purchase futures contracts to immediately invest incoming cash in the market, or sell futures in response to cash outflows, thereby simulating a fully invested position in the underlying index while maintaining a cash balance for liquidity. The fund may seek to enhance returns by using futures contracts instead of the underlying securities when futures are believed to be priced more attractively than the underlying securities. The primary risks associated with the use of futures contracts are imperfect correlation between changes in market values of stocks held by the fund and the prices of futures contracts, and the possibility of an illiquid market.

Futures contracts are valued at their quoted daily settlement prices. The aggregate principal amounts of the contracts are not recorded in the Statement of Net Assets. Fluctuations in the value of the contracts are recorded in the Statement of Net Assets as an asset (liability) and in the Statement of Operations as unrealized appreciation (depreciation) until the contracts are closed, when they are recorded as realized futures gains (losses).

3. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its taxable income. Accordingly, no provision for federal income taxes is required in the financial statements.

4. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

5. Security Lending: The fund may lend its securities to qualified institutional borrowers to earn additional income. Security loans are required to be secured at all times by collateral at least equal to the market value of securities loaned. The fund invests cash collateral received in Vanguard Market

21

Liquidity Fund, and records a liability for the return of the collateral, during the period the securities are on loan. Security lending income represents the income earned on investing cash collateral, less expenses associated with the loan.

6. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold.

Each class of shares has equal rights as to assets and earnings, except that each class separately bears certain class-specific expenses related to maintenance of shareholder accounts (included in Management and Administrative expenses) and shareholder reporting. Marketing and distribution expenses are allocated to each class of shares based on a method approved by the board of trustees. Income, other non-class-specific expenses, and gains and losses on investments are allocated to each class of shares based on its relative net assets.

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At December 31, 2006, the fund had contributed capital of $7,047,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 7.04% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

C. Distributions are determined on a tax basis and may differ from net investment income and realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when certain items of income, expense, gain, or loss are recognized in different periods for financial statement and tax purposes; these differences will reverse at some time in the future. Differences in classification may also result from the treatment of short-term gains as ordinary income for tax purposes.

During the year ended December 31, 2006, the fund realized $344,693,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchange fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

For tax purposes, at December 31, 2006, the fund had $15,978,000 of ordinary income available for distribution. The fund had available realized losses of $6,571,975,000 to offset future net capital gains of $193,358,000 through December 31, 2008, $890,248,000 through December 31, 2009, $3,087,963,000 through December 31, 2010, $145,498,000 through December 31, 2011, $44,874,000 through December 31, 2012, $757,853,000 through December 31, 2013, $1,156,454,000 through December 31, 2014, and $295,727,000 through December 31, 2015.

At December 31, 2006, the cost of investment securities for tax purposes was $72,264,866,000. Net unrealized appreciation of investment securities for tax purposes was $46,885,577,000, consisting of unrealized gains of $51,548,019,000 on securities that had risen in value since their purchase and $4,662,442,000 in unrealized losses on securities that had fallen in value since their purchase.

22

At December 31, 2006, the aggregate settlement value of open futures contracts expiring in March 2007 and the related unrealized appreciation (depreciation) were:

			($000)
		Aggregate	Unrealized
	Number of	Settlement	Appreciation
Futures Contracts	Long Contracts	Value	(Depreciation)
S&P 500 Index	1,278	456,374	1,595
E-mini S&P 500 Index	550	39,281	(146)

Unrealized appreciation (depreciation) on open futures contracts is required to be treated as realized gain (loss) for tax purposes.

D. During the year ended December 31, 2006, the fund purchased $5,384,897,000 of investment securities and sold $8,366,126,000 of investment securities other than temporary cash investments.

E. The market value of securities on loan to broker-dealers at December 31, 2006, was $38,777,000, for which the fund received cash collateral of $40,704,000.

G. In June 2006, the Financial Accounting Standards Board issued Interpretation No. 48 (“FIN 48”), “Accounting for Uncertainty in Income Taxes.” FIN 48 establishes the minimum threshold for recognizing, and a system for measuring, the benefits of tax-return positions in financial statements. FIN 48 will be effective for the fund’s fiscal year ending December 31, 2007. Management is in the process of analyzing the fund’s tax positions for purposes of implementing FIN 48; based on the analysis completed to date, management does not believe the adoption of FIN 48 will result in any material impact to the fund’s financial statements.

Report of Independent Registered Public Accounting Firm

To the Trustees of Vanguard Index Funds and Shareholders of Vanguard 500 Index Fund:

In our opinion, the accompanying statement of net assets and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Vanguard 500 Index Fund (one of the funds constituting Vanguard Index Funds, hereafter referred to as the “Fund”) at December 31, 2006, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the periods indicated, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at December 31, 2006 by correspondence with the custodian and broker and by agreement to the underlying ownership records for the Vanguard Market Liquidity Fund, provide a reasonable basis for our opinion.

Special 2006 tax information (unaudited) for Vanguard 500 Index Fund

This information for the fiscal year ended December 31, 2006, is included pursuant to provisions of the Internal Revenue Code.

The fund distributed $1,992,896,000 of qualified dividend income to shareholders during the fiscal year.

For corporate shareholders, 100% of investment income (dividend income plus short-term gains, if any) qualifies for the dividends-received deduction.

Your Fund’s After-Tax Returns

This table presents returns for your fund both before and after taxes. The after-tax returns are shown in two ways: (1) assuming that an investor owned the fund during the entire period and paid taxes on the fund’s distributions, and (2) assuming that an investor paid taxes on the fund’s distributions and sold all shares at the end of each period.

Calculations are based on the highest individual federal income tax and capital gains tax rates in effect at the times of the distributions and the hypothetical sales. State and local taxes were not considered. After-tax returns reflect any qualified dividend income. (In the example, returns after the sale of fund shares may be higher than those assuming no sale. This occurs when the sale would have produced a capital loss. The calculation assumes that the investor received a tax deduction for the loss.)

The table shows returns for Investor Shares only; returns for other share classes will differ. Please note that your actual after-tax returns will depend on your tax situation and may differ from those shown. Also note that if you own the fund in a tax-deferred account, such as an individual retirement account or a 401(k) plan, this information does not apply to you. Such accounts are not subject to current taxes.

Finally, keep in mind that a fund’s performance—whether before or after taxes—does not guarantee future results.

About Your Fund’s Expenses

As a shareholder of the fund, you incur ongoing costs, which include costs for portfolio management, administrative services, and shareholder reports (like this one), among others. Operating expenses, which are deducted from a fund’s gross income, directly reduce the investment return of the fund.

A fund’s expenses are expressed as a percentage of its average net assets. This figure is known as the expense ratio. The following examples are intended to help you understand the ongoing costs (in dollars) of investing in your fund and to compare these costs with those of other mutual funds. The examples are based on an investment of $1,000 made at the beginning of the period shown and held for the entire period.

The table below illustrates your fund’s costs in two ways:

• Based on actual fund return. This section helps you to estimate the actual expenses that you paid over the period. The “Ending Account Value” shown is derived from the fund’s actual return, and the third column shows the dollar amount that would have been paid by an investor who started with $1,000 in the fund. You may use the information here, together with the amount you invested, to estimate the expenses that you paid over the period.

To do so, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number given for your fund under the heading “Expenses Paid During Period.”

• Based on hypothetical 5% yearly return. This section is intended to help you compare your fund’s costs with those of other mutual funds. It assumes that the fund had a yearly return of 5% before expenses, but that the expense ratio is unchanged. In this case—because the return used is not the fund’s actual return—the results do not apply to your investment. The example is useful in making comparisons because the Securities and Exchange Commission requires all mutual funds to calculate expenses based on a 5% return. You can assess your fund’s costs by comparing this hypothetical example with the hypothetical examples that appear in shareholder reports of other funds.

1 This table does not include data for share classes with fewer than six months of history.

2 The calculations are based on expenses incurred in the most recent six-month period. The fund’s annualized six-month expense ratios for that period are 0.17% for Investor Shares and 0.09% for Admiral Shares. The dollar amounts shown as “Expenses Paid” are equal to the annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent six-month period, then divided by the number of days in the most recent 12-month period.

27

Note that the expenses shown in the table on page 27 are meant to highlight and help you compare ongoing costs only and do not reflect any transactional costs or account maintenance fees. They do not include your fund’s low-balance fee, which is described in the prospectus. If this fee were applied to your account, your costs would be higher. Your fund does not charge transaction fees, such as purchase or redemption fees, nor does it carry a “sales load.”

The calculations assume no shares were bought or sold during the period. Your actual costs may have been higher or lower, depending on the amount of your investment and the timing of any purchases or redemptions.

You can find more information about the fund’s expenses, including annual expense ratios, in the Financial Statements section of this report. For additional information on operating expenses and other shareholder costs, please refer to the appropriate fund prospectus.

Glossary

Beta. A measure of the magnitude of a fund’s past share-price fluctuations in relation to the ups and downs of a given market index. The index is assigned a beta of 1.00. Compared with a given index, a fund with a beta of 1.20 typically would have seen its share price rise or fall by 12% when the index rose or fell by 10%. A fund’s beta should be reviewed in conjunction with its R-squared (see definition below). The lower the R-squared, the less correlation there is between the fund and the index, and the less reliable beta is as an indicator of volatility.

Earnings Growth Rate. The average annual rate of growth in earnings over the past five years for the stocks now in a fund.

Expense Ratio. The percentage of a fund’s average net assets used to pay its annual administrative and advisory expenses. These expenses directly reduce returns to investors.

Foreign Holdings. The percentage of a fund represented by stocks or depositary receipts of companies based outside the United States.

Inception Date. The date on which the assets of a fund (or one of its share classes) are first invested in accordance with the fund’s investment objective. For funds with a subscription period, the inception date is the day after that period ends. Investment performance is measured from the inception date.

Median Market Cap. An indicator of the size of companies in which a fund invests; the midpoint of market capitalization (market price x shares outstanding) of a fund’s stocks, weighted by the proportion of the fund’s assets invested in each stock. Stocks representing half of the fund’s assets have market capitalizations above the median, and the rest are below it.

Price/Book Ratio. The share price of a stock divided by its net worth, or book value, per share. For a fund, the weighted average price/book ratio of the stocks it holds.

Price/Earnings Ratio. The ratio of a stock’s current price to its per-share earnings over the past year. For a fund, the weighted average P/E of the stocks it holds. P/E is an indicator of market expectations about corporate prospects; the higher the P/E, the greater the expectations for a company’s future growth.

R-Squared. A measure of how much of a fund’s past returns can be explained by the returns from the market in general, as measured by a given index. If a fund’s total returns were precisely synchronized with an index’s returns, its R-squared would be 1.00. If the fund’s returns bore no relationship to the index’s returns, its R-squared would be 0.

Return on Equity. The annual average rate of return generated by a company during the past five years for each dollar of shareholder’s equity (net income divided by shareholder’s equity). For a fund, the weighted average return on equity for the companies whose stocks it holds.

Short-Term Reserves. The percentage of a fund invested in highly liquid, short-term securities that can be readily converted to cash.

Turnover Rate. An indication of the fund’s trading activity. Funds with high turnover rates incur higher transaction costs and may be more likely to distribute capital gains (which may be taxable to investors). The turnover rate excludes in-kind transactions, which have minimal impact on costs.

Yield. A snapshot of a fund’s income from interest and dividends. The yield, expressed as a percentage of the fund’s net asset value, is based on income earned over the past 30 days and is annualized, or projected forward for the coming year. The index yield is based on the current annualized rate of income provided by securities in the index.

The People Who Govern Your Fund

The trustees of your mutual fund are there to see that the fund is operated and managed in your best interests since, as a shareholder, you are a part owner of the fund. Your fund’s trustees also serve on the board of directors of The Vanguard Group, Inc., which is owned by the Vanguard funds and provides services to them on an at-cost basis.

A majority of Vanguard’s board members are independent, meaning that they have no affiliation with Vanguard or the funds they oversee, apart from the sizable personal investments they have made as private individuals.

Our independent board members bring distinguished backgrounds in business, academia, and public service to their task of working with Vanguard officers to establish the policies and oversee the activities of the funds. Among board members’ responsibilities are selecting investment advisors for the funds; monitoring fund operations, performance, and costs; reviewing contracts; nominating and selecting new trustees/directors; and electing Vanguard officers.

Each trustee serves a fund until its termination; or until the trustee’s retirement, resignation, or death; or otherwise as specified in the fund’s organizational documents. Any trustee may be removed at a shareholders’ meeting by a vote representing two-thirds of the net asset value of all shares of the fund together with shares of other Vanguard funds organized within the same trust. The table on these two pages shows information for each trustee and executive officer of the fund. The mailing address of the trustees and officers is P.O. Box 876, Valley Forge, PA 19482.

Chairman’s Letter

Dear Shareholder,

For the fiscal year ended December 31, all three Vanguard Small-Cap Index Funds tracked their indexes with precision and delivered healthy returns. In the small-capitalization arena, value-oriented stocks outperformed their growth counterparts by a considerable margin. The returns for all three Vanguard funds were superior to the average returns produced by their peers.

For taxable investors, it’s worth noting that the benefits of holding index funds can be even greater, as the funds’ low turnover and Vanguard’s disciplined management generally limit the distribution of realized capital gains. During 2006, none of the small-cap index funds distributed a capital gain. (For a report on the funds’ after-tax returns, see page 60.)

Strong second half pushed stocks to new high

Beginning in mid-July, stocks climbed steadily through the remainder of the year, with the Dow Jones Industrial Average setting a record high on December 27. For the year, the broad U.S. stock market gained 15.9%. Despite a soft housing sector and ongoing troubles within the U.S. auto industry, the economy continued to grow and corporate profits remained strong.

For the year, small-capitalization stocks beat out large-cap issues, and value stocks outperformed their growth-oriented counterparts. International stocks continued

to best domestic equities, particularly in emerging markets and Europe. A declining dollar further enhanced returns abroad for U.S.-based investors.

Bond returns remained modest as the Fed paused its rate hikes

The Federal Reserve Board extended its money-tightening campaign during the first half of the year, raising its target for the federal funds rate four times. The Fed then paused, leaving the target rate unchanged at 5.25% for the rest of the year, and inflation fears eased. Bond yields declined in the second half of the year, and short-term yields were higher than longer-term yields.

Fixed income returns for 2006 were modest, with the broad taxable bond market returning 4.3% and municipal bonds providing 4.8%.

2006 was a healthy year for small-cap stocks

In a robust market environment for stocks, small-cap stocks performed very well over the past 12 months. The Investor Shares of the Vanguard small-cap index funds produced returns ranging from 19.2% for the Small-Cap Value Index Fund to 11.9% for the Small-Cap Growth Index Fund.

The Small-Cap Index Fund, which combines the holdings of the two other funds, returned 15.6%. Results for all three funds were

superior to the average returns produced by their peer groups, which are largely actively managed funds.

Vanguard Quantitative Equity Group, which oversees the funds, once again succeeded in making sure each one closely tracked the performance of its target index. These results are a tribute to the adept portfolio-construction and trading methodologies continuously refined by the group.

The performance of the three funds reflected their respective weightings in the market’s different industry sectors. For example, the Small-Cap Value Fund had about 37% of its assets in financial stocks, which experienced healthy gains, particularly for banks and real estate investment trusts. In contrast, the Small-Cap Growth Fund had a sizable exposure (22% of assets) to the information technology sector, which produced more modest returns.

Each of the three funds held a different double-digit weighting in the industrials sector, which performed particularly well in 2006. There were detractors among the sectors as well, particularly the struggling homebuilding industry within the consumer discretionary sector, where poor performance dragged on returns for each of the funds.

Long-term returns show the value of indexing

Indexing is a long-term strategy, and over time the benefits of its market-matching approach become clear. While there will inevitably be years when the funds’ actively managed competitors perform better, it’s

no surprise when index funds outperform their competition, as each of the three small-cap index funds did in 2006.

The table below shows how the three funds have performed over the longer term in comparison with their competitors and target benchmarks. The table also shows what would have become of a hypothetical $10,000 initial investment in each fund’s Investor Shares. The Small-Cap Index Fund, for example, returned an average of 10.0% a year, which would have transformed the $10,000 initial investment into $25,993. The Small-Cap Growth and Value Index Funds are “younger”—they were opened in 1998—and the 2000–2002 bear market therefore figures more prominently in their long-term performance. Since inception, average annual returns for these two funds have been 8.1% and 10.2%, respectively.

The table also shows that two of the funds trailed the average returns of their peer groups. That is largely because, until 2003, the funds tracked indexes that did not reflect the small-cap stock market as it is viewed by active investment managers. Since May 2003, the funds have targeted indexes from Morgan Stanley Capital International that better represent the market from an active investment standpoint. We believe that, in the future, differences between the returns of these index funds and the average results of their actively managed competitors should depend more

The figures shown represent past performance, which is not a guarantee of future results. (Current performance may be lower or higher than the performance data cited. For performance data current to the most recent month-end, visit our website at www.vanguard.com.) Note, too, that both investment returns and principal value can fluctuate widely, so an investor’s shares, when sold, could be worth more or less than their original cost.

on costs than on any other factor. Because Vanguard funds historically have maintained exceptionally low costs, this is an advantage that may well compound for investors over time. (For a comparison of expense ratios, see the table on page 4.)

Investors need perspective and a balanced strategy

In 2006, all of the Vanguard small-cap index funds outperformed their peer-group averages. While this 12-month performance is gratifying, we generally counsel investors that neither under- nor outperformance is all that meaningful in the short term. In fact, we always encourage Vanguard shareholders to evaluate their investments from a long-term perspective.

Sticking with a carefully considered, balanced portfolio of stock, bond, and money market mutual funds suited to your unique circumstances can be key to your long-term investing success.

As an investor, you can weather the market’s uncertainties by holding to a well-planned strategy. We believe that investing in Vanguard’s small-cap index funds is a smart way to capitalize on this important segment of the total stock market.

Thank you for investing with Vanguard.

Sincerely,

John J. Brennan

Chairman and Chief Executive Officer

Vanguard Small-Cap Index Fund

Notes to Financial Statements

Vanguard Small-Cap Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers five classes of shares: Investor Shares, Admiral Shares, Signal Shares, Institutional Shares, and ETF Shares. Investor Shares are available to any investor who meets the fund’s minimum purchase requirements. Admiral Shares are designed for investors who meet certain administrative, servicing, tenure, and account-size criteria. Signal Shares are designed for institutional investors who meet certain administrative, servicing, and account-size criteria. Signal Shares were first issued on December 15, 2006. Institutional Shares are designed for investors who meet certain administrative and servicing criteria and invest a minimum of $5 million. ETF Shares are listed for trading on the American Stock Exchange; they can be purchased and sold through a broker.

A. The following significant accounting policies conform to generally accepted accounting principles for U.S. mutual funds. The fund consistently follows such policies in preparing its financial statements.

1. Security Valuation: Securities are valued as of the close of trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the valuation date. Equity securities are valued at the latest quoted sales prices or official closing prices taken from the primary market in which each security trades; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Securities for which market quotations are not readily available, or whose values have been materially affected by events occurring before the fund’s pricing time but after the close of the securities’ primary markets, are valued by methods deemed by the board of trustees to represent fair value. Investments in Vanguard Market Liquidity Fund are valued at that fund’s net asset value. Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value.

2. Futures Contracts: The fund uses index futures contracts to a limited extent, with the objectives of maintaining full exposure to the stock market, enhancing returns, maintaining liquidity, and minimizing transaction costs. The fund may purchase futures contracts to immediately invest incoming cash in the market, or sell futures in response to cash outflows, thereby simulating a fully invested position in the underlying index while maintaining a cash balance for liquidity. The fund may seek to enhance returns by using futures contracts instead of the underlying securities when futures are believed to be priced more attractively than the underlying securities. The primary risks associated with the use of futures contracts are imperfect correlation between changes in market values of stocks held by the fund and the prices of futures contracts, and the possibility of an illiquid market.

Futures contracts are valued at their quoted daily settlement prices. The aggregate principal amounts of the contracts are not recorded in the Statement of Net Assets. Fluctuations in the value of the contracts are recorded in the Statement of Net Assets as an asset (liability) and in the Statement of Operations as unrealized appreciation (depreciation) until the contracts are closed, when they are recorded as realized futures gains (losses).

3. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its taxable income. Accordingly, no provision for federal income taxes is required in the financial statements.

4. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

23

Vanguard Small-Cap Index Fund

5. Security Lending: The fund may lend its securities to qualified institutional borrowers to earn additional income. Security loans are required to be secured at all times by collateral at least equal to the market value of securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability for the return of the collateral, during the period the securities are on loan. Security lending income represents the income earned on investing cash collateral, less expenses associated with the loan.

6. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold.

Each class of shares has equal rights as to assets and earnings, except that each class separately bears certain class-specific expenses related to maintenance of shareholder accounts (included in Management and Administrative expenses) and shareholder reporting. Marketing and distribution expenses are allocated to each class of shares based on a method approved by the board of trustees. Income, other non-class-specific expenses, and gains and losses on investments are allocated to each class of shares based on its relative net assets.

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At December 31, 2006, the fund had contributed capital of $1,355,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 1.35% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

C. Distributions are determined on a tax basis and may differ from net investment income and realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when certain items of income, expense, gain, or loss are recognized in different periods for financial statement and tax purposes; these differences will reverse at some time in the future. Differences in classification may also result from the treatment of short-term gains as ordinary income for tax purposes.

During the year ended December 31, 2006, the fund realized $694,982,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchange fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized gains to paid-in capital.

For tax purposes, at December 31, 2006, the fund had $2,188,000 of ordinary income available for distribution. The fund had available realized losses of $402,458,000 to offset future net capital gains of $326,341,000 through December 31, 2011, and $76,117,000 through December 31, 2015.

At December 31, 2006, the cost of investment securities for tax purposes was $10,619,573,000. Net unrealized appreciation of investment securities for tax purposes was $3,686,107,000, consisting of unrealized gains of $4,137,633,000 on securities that had risen in value since their purchase and $451,526,000 in unrealized losses on securities that had fallen in value since their purchase.

At December 31, 2006, the aggregate settlement value of open futures contracts expiring in March 2007 and the related unrealized appreciation (depreciation) were:

			($000)
		Aggregate	Unrealized
	Number of	Settlement	Appreciation
Futures Contracts	Long Contracts	Value	(Depreciation)
E-mini Russell 2000 Index	50	3,975	(37)

24

Vanguard Small-Cap Index Fund

Unrealized appreciation (depreciation) on open futures contracts is required to be treated as realized gain (loss) for tax purposes.

D. During the year ended December 31, 2006, the fund purchased $4,597,300,000 of investment securities and sold $2,984,295,000 of investment securities other than temporary cash investments.

E. The market value of securities on loan to broker-dealers at December 31, 2006, was $450,844,000, for which the fund received cash collateral of $479,520,000.

F. Capital share transactions for each class of shares were:

G. In June 2006, the Financial Accounting Standards Board issued Interpretation No. 48 (“FIN 48”), “Accounting for Uncertainty in Income Taxes". FIN 48 establishes the minimum threshold for recognizing, and a system for measuring, the benefits of tax-return positions in financial statements. FIN 48 will be effective for the fund’s fiscal year ending December 31, 2007. Management is in the process of analyzing the fund’s tax positions for purposes of implementing FIN 48; based on the analysis completed to date, management does not believe the adoption of FIN 48 will result in any material impact to the fund’s financial statements.

Vanguard Small-Cap Growth Index Fund

Notes to Financial Statements

Vanguard Small-Cap Growth Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers three classes of shares: Investor Shares, Institutional Shares, and ETF Shares. Investor Shares are available to any investor who meets the fund’s minimum purchase requirements. Institutional Shares are designed for investors who meet certain administrative and servicing criteria and invest a minimum of $5 million. ETF Shares are listed for trading on the American Stock Exchange; they can be purchased and sold through a broker.

A. The following significant accounting policies conform to generally accepted accounting principles for U.S. mutual funds. The fund consistently follows such policies in preparing its financial statements.

1. Security Valuation: Securities are valued as of the close of trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the valuation date. Equity securities are valued at the latest quoted sales prices or official closing prices taken from the primary market in which each security trades; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Securities for which market quotations are not readily available, or whose values have been materially affected by events occurring before the fund’s pricing time but after the close of the securities’ primary markets, are valued by methods deemed by the board of trustees to represent fair value. Investments in Vanguard Market Liquidity Fund are valued at that fund’s net asset value. Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value.

2. Futures Contracts: The fund uses index futures contracts to a limited extent, with the objectives of maintaining full exposure to the stock market, enhancing returns, maintaining liquidity, and minimizing transaction costs. The fund may purchase futures contracts to immediately invest incoming cash in the market, or sell futures in response to cash outflows, thereby simulating a fully invested position in the underlying index while maintaining a cash balance for liquidity. The fund may seek to enhance returns by using futures contracts instead of the underlying securities when futures are believed to be priced more attractively than the underlying securities. The primary risks associated with the use of futures contracts are imperfect correlation between changes in market values of stocks held by the fund and the prices of futures contracts, and the possibility of an illiquid market.

Futures contracts are valued at their quoted daily settlement prices. The aggregate principal amounts of the contracts are not recorded in the Statement of Net Assets. Fluctuations in the value of the contracts are recorded in the Statement of Net Assets as an asset (liability) and in the Statement of Operations as unrealized appreciation (depreciation) until the contracts are closed, when they are recorded as realized futures gains (losses).

3. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its taxable income. Accordingly, no provision for federal income taxes is required in the financial statements.

4. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

38

Vanguard Small-Cap Growth Index Fund

5. Security Lending: The fund may lend its securities to qualified institutional borrowers to earn additional income. Security loans are required to be secured at all times by collateral at least equal to the market value of securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability for the return of the collateral, during the period the securities are on loan. Security lending income represents the income earned on investing cash collateral, less expenses associated with the loan.

6. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold.

Each class of shares has equal rights as to assets and earnings, except that each class separately bears certain class-specific expenses related to maintenance of shareholder accounts (included in Management and Administrative expenses) and shareholder reporting. Marketing and distribution expenses are allocated to each class of shares based on a method approved by the board of trustees. Income, other non-class-specific expenses, and gains and losses on investments are allocated to each class of shares based on its relative net assets.

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At December 31, 2006, the fund had contributed capital of $289,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.29% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

C. Distributions are determined on a tax basis and may differ from net investment income and realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when certain items of income, expense, gain, or loss are recognized in different periods for financial statement and tax purposes; these differences will reverse at some time in the future. Differences in classification may also result from the treatment of short-term gains as ordinary income for tax purposes.

During the year ended December 31, 2006, the fund realized $151,028,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchange fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized gains to paid-in capital.

For tax purposes, at December 31, 2006, the fund had $184,000 of ordinary income available for distribution. The fund had available realized losses of $59,847,000 to offset future net capital gains of $13,814,000 through December 31, 2011, $15,893,000 through December 31, 2014, and $30,140,000 through December 31, 2015.

At December 31, 2006, the cost of investment securities for tax purposes was $2,571,162,000. Net unrealized appreciation of investment securities for tax purposes was $513,860,000, consisting of unrealized gains of $610,361,000 on securities that had risen in value since their purchase and $96,501,000 in unrealized losses on securities that had fallen in value since their purchase.

Vanguard Small-Cap Growth Index Fund

At December 31, 2006, the aggregate settlement value of open futures contracts expiring in March 2007 and the related unrealized appreciation (depreciation) were:

		($000)
		Aggregate	Unrealized
	Number of	Settlement	Appreciation
Futures Contracts	Long Contracts	Value	(Depreciation)
E-mini Russell 2000 Index	130	10,334	(71)
Russell 2000 Index	24	9,539	(51)

Unrealized appreciation (depreciation) on open futures contracts is required to be treated as realized gain (loss) for tax purposes.

D. During the year ended December 31, 2006, the fund purchased $2,111,948,000 of investment securities and sold $1,404,094,000 of investment securities other than temporary cash investments.

E. The market value of securities on loan to broker-dealers at December 31, 2006, was $100,172,000, for which the fund received cash collateral of $106,145,000.

F. Capital share transactions for each class of shares were:

Vanguard Small-Cap Growth Index Fund

G. In June 2006, the Financial Accounting Standards Board issued Interpretation No. 48 (“FIN 48”), “Accounting for Uncertainty in Income Taxes.” FIN 48 establishes the minimum threshold for recognizing, and a system for measuring, the benefits of tax-return positions in financial statements. FIN 48 will be effective for the fund’s fiscal year ending December 31, 2007. Management is in the process of analyzing the fund’s tax positions for purposes of implementing FIN 48; based on the analysis completed to date, management does not believe the adoption of FIN 48 will result in any material impact to the fund’s financial statements.

Performance Summary

All of the returns in this report represent past performance, which is not a guarantee of future results that may be achieved by the fund. (Current performance may be lower or higher than the performance data cited. For performance data current to the most recent month-end, visit our website at www.vanguard.com.) Note, too, that both investment returns and principal value can fluctuate widely, so an investor’s shares, when sold, could be worth more or less than their original cost.

Vanguard Small-Cap Value Index Fund

Notes to Financial Statements

Vanguard Small-Cap Value Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers three classes of shares: Investor Shares, Institutional Shares, and ETF Shares. Investor Shares are available to any investor who meets the fund’s minimum purchase requirements. Institutional Shares are designed for investors who meet certain administrative and servicing criteria and invest a minimum of $5 million. ETF Shares are listed for trading on the American Stock Exchange; they can be purchased and sold through a broker.

A. The following significant accounting policies conform to generally accepted accounting principles for U.S. mutual funds. The fund consistently follows such policies in preparing its financial statements.

1. Security Valuation: Securities are valued as of the close of trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the valuation date. Equity securities are valued at the latest quoted sales prices or official closing prices taken from the primary market in which each security trades; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Securities for which market quotations are not readily available, or whose values have been materially affected by events occurring before the fund’s pricing time but after the close of the securities’ primary markets, are valued by methods deemed by the board of trustees to represent fair value. Investments in Vanguard Market Liquidity Fund are valued at that fund’s net asset value. Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value.

2. Futures Contracts: The fund uses index futures contracts to a limited extent, with the objectives of maintaining full exposure to the stock market, enhancing returns, maintaining liquidity, and minimizing transaction costs. The fund may purchase futures contracts to immediately invest incoming cash in the market, or sell futures in response to cash outflows, thereby simulating a fully invested position in the underlying index while maintaining a cash balance for liquidity. The fund may seek to enhance returns by using futures contracts instead of the underlying securities when futures are believed to be priced more attractively than the underlying securities. The primary risks associated with the use of futures contracts are imperfect correlation between changes in market values of stocks held by the fund and the prices of futures contracts, and the possibility of an illiquid market.

Futures contracts are valued at their quoted daily settlement prices. The aggregate principal amounts of the contracts are not recorded in the Statement of Net Assets. Fluctuations in the value of the contracts are recorded in the Statement of Net Assets as an asset (liability) and in the Statement of Operations as unrealized appreciation (depreciation) until the contracts are closed, when they are recorded as realized futures gains (losses).

3. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its taxable income. Accordingly, no provision for federal income taxes is required in the financial statements.

4. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

54

Vanguard Small-Cap Value Index Fund

5. Security Lending: The fund may lend its securities to qualified institutional borrowers to earn additional income. Security loans are required to be secured at all times by collateral at least equal to the market value of securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability for the return of the collateral, during the period the securities are on loan. Security lending income represents the income earned on investing cash collateral, less expenses associated with the loan.

6. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold.

Each class of shares has equal rights as to assets and earnings, except that each class separately bears certain class-specific expenses related to maintenance of shareholder accounts (included in Management and Administrative expenses) and shareholder reporting. Marketing and distribution expenses are allocated to each class of shares based on a method approved by the board of trustees. Income, other non-class-specific expenses, and gains and losses on investments are allocated to each class of shares based on its relative net assets.

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At December 31, 2006, the fund had contributed capital of $495,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.49% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

C. Distributions are determined on a tax basis and may differ from net investment income and realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when certain items of income, expense, gain, or loss are recognized in different periods for financial statement and tax purposes; these differences will reverse at some time in the future. Differences in classification may also result from the treatment of short-term gains as ordinary income for tax purposes.

During the year ended December 31, 2006, the fund realized $376,968,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchange fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized gains to paid-in capital.

For tax purposes, at December 31, 2006, the fund had $3,927,000 of ordinary income available for distribution. The fund had available realized losses of $80,822,000 to offset future net capital gains of $67,032,000 through December 31, 2011, and $13,790,000 through December 31, 2015.

At December 31, 2006, the cost of investment securities for tax purposes was $4,305,348,000. Net unrealized appreciation of investment securities for tax purposes was $919,361,000, consisting of unrealized gains of $1,037,816,000 on securities that had risen in value since their purchase and $118,455,000 in unrealized losses on securities that had fallen in value since their purchase.

Vanguard Small-Cap Value Index Fund

At December 31, 2006, the aggregate settlement value of open futures contracts expiring in March 2007 and the related unrealized appreciation (depreciation) were:

		($000)
		Aggregate	Unrealized
	Number of	Settlement	Appreciation
Futures Contracts	Long Contracts	Value	(Depreciation)
E-mini Russell 2000 Index	190	15,103	(150)
Russell 2000 Index	18	7,154	(14)

Unrealized appreciation (depreciation) on open futures contracts is required to be treated as realized gain (loss) for tax purposes.

D. During the year ended December 31, 2006, the fund purchased $2,614,859,000 of investment securities and sold $2,054,430,000 of investment securities other than temporary cash investments.

E. The market value of securities on loan to broker-dealers at December 31, 2006, was $86,668,000, for which the fund received cash collateral of $91,554,000.

F. Capital share transactions for each class of shares were:

Vanguard Small-Cap Value Index Fund

G. In June 2006, the Financial Accounting Standards Board issued Interpretation No. 48 (“FIN 48”), “Accounting for Uncertainty in Income Taxes.” FIN 48 establishes the minimum threshold for recognizing, and a system for measuring, the benefits of tax-return positions in financial statements. FIN 48 will be effective for the fund’s fiscal year ending December 31, 2007. Management is in the process of analyzing the fund’s tax positions for purposes of implementing FIN 48; based on the analysis completed to date, management does not believe the adoption of FIN 48 will result in any material impact to the fund’s financial statements.

Report of Independent Registered

Public Accounting Firm

To the Trustees of Vanguard Index Funds and Shareholders of Vanguard Small-Cap Index Fund, Vanguard Small-Cap Growth Index Fund and Vanguard Small-Cap Value Index Fund:

In our opinion, the accompanying statements of net assets—investments summary and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Vanguard Small-Cap Index Fund, Vanguard Small-Cap Growth Index Fund and Vanguard Small-Cap Value Index Fund (separate funds of Vanguard Index Funds, hereafter referred to as the “Funds”) at December 31, 2006, the results of each of their operations for the year then ended, the changes in each of their net assets for each of the two years in the period then ended and the financial highlights for each of the periods indicated, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Funds’ management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at December 31, 2006 by correspondence with the custodian and broker and by agreement to the underlying ownership records for Vanguard Market Liquidity Fund, provide a reasonable basis for our opinion.

Your Fund’s After-Tax Returns

This table presents returns for your fund both before and after taxes. The after-tax returns are shown in two ways: (1) assuming that an investor owned the fund during the entire period and paid taxes on the fund’s distributions, and (2) assuming that an investor paid taxes on the fund’s distributions and sold all shares at the end of each period.

Calculations are based on the highest individual federal income tax and capital gains tax rates in effect at the times of the distributions and the hypothetical sales. State and local taxes were not considered. After-tax returns reflect any qualified dividend income. (In the example, returns after the sale of fund shares may be higher than those assuming no sale. This occurs when the sale would have produced a capital loss. The calculation assumes that the investor received a tax deduction for the loss.)

The table shows returns for Investor Shares only; returns for other share classes will differ. Please note that your actual after-tax returns will depend on your tax situation and may differ from those shown. Also note that if you own the fund in a tax-deferred account, such as an individual retirement account or a 401(k) plan, this information does not apply to you. Such accounts are not subject to current taxes.

Finally, keep in mind that a fund’s performance—whether before or after taxes—does not guarantee future results.

About Your Fund’s Expenses

As a shareholder of the fund, you incur ongoing costs, which include costs for portfolio management, administrative services, and shareholder reports (like this one), among others. Operating expenses, which are deducted from a fund’s gross income, directly reduce the investment return of the fund.

A fund’s expenses are expressed as a percentage of its average net assets. This figure is known as the expense ratio. The following examples are intended to help you understand the ongoing costs (in dollars) of investing in your fund and to compare these costs with those of other mutual funds. The examples are based on an investment of $1,000 made at the beginning of the period shown and held for the entire period.

The table on page 62 illustrates your fund’s costs in two ways:

• Based on actual fund return. This section helps you to estimate the actual expenses that you paid over the period. The “Ending Account Value” shown is derived from the fund’s actual return, and the third column shows the dollar amount that would have been paid by an investor who started with $1,000 in the fund. You may use the information here, together with the amount you invested, to estimate the expenses that you paid over the period.

To do so, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number given for your fund under the heading “Expenses Paid During Period.”

• Based on hypothetical 5% yearly return. This section is intended to help you compare your fund’s costs with those of other mutual funds. It assumes that the fund had a yearly return of 5% before expenses, but that the expense ratio is unchanged. In this case—because the return used is not the fund’s actual return—the results do not apply to your investment. The example is useful in making comparisons because the Securities and Exchange Commission requires all mutual funds to calculate expenses based on a 5% return. You can assess your fund’s costs by comparing this hypothetical example with the hypothetical examples that appear in shareholder reports of other funds.

Note that the expenses shown in the table on page 62 are meant to highlight and help you compare ongoing costs only and do not reflect any transactional costs or account maintenance fees. They do not include your fund’s low-balance fee, which is described in the prospectus. If this fee were applied to your account, your costs would be higher. Your fund does not charge transaction fees, such as purchase or redemption fees, nor does it carry a “sales load.”

The calculations assume no shares were bought or sold during the period. Your actual costs may have been higher or lower, depending on the amount of your investment and the timing of any purchases or redemptions.

You can find more information about the funds’ expenses, including annual expense ratios, in the Financial Statements section of this report. For additional information on operating expenses and other shareholder costs, please refer to the appropriate fund prospectus.

1 This table does not include data for funds or share classes of funds with fewer than six months of history.

2 The calculations are based on expenses incurred in the most recent six-month period. The funds’ annualized six-month expense ratios for that period are: for the Small-Cap Index Fund, 0.22% for Investor Shares, 0.12% for Admiral Shares, 0.07% for Institutional Shares, and 0.09% for ETF Shares; for the Small-Cap Growth Index Fund, 0.23% for Investor Shares, 0.07% for Institutional Shares, and 0.11% for ETF Shares; for the Small-Cap Value Index Fund, 0.22% for Investor Shares, 0.07% for Institutional Shares, and 0.11% for ETF Shares. The dollar amounts shown as “Expenses Paid” are equal to the annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent six-month period, then divided by the number of days in the most recent 12-month period.

Glossary

Beta. A measure of the magnitude of a fund’s past share-price fluctuations in relation to the ups and downs of a given market index. The index is assigned a beta of 1.00. Compared with a given index, a fund with a beta of 1.20 typically would have seen its share price rise or fall by 12% when the index rose or fell by 10%. A fund’s beta should be reviewed in conjunction with its R-squared (see definition below). The lower the R-squared, the less correlation there is between the fund and the index, and the less reliable beta is as an indicator of volatility.

Earnings Growth Rate. The average annual rate of growth in earnings over the past five years for the stocks now in a fund.

Expense Ratio. The percentage of a fund’s average net assets used to pay its annual administrative and advisory expenses. These expenses directly reduce returns to investors.

Foreign Holdings. The percentage of a fund represented by stocks or depositary receipts of companies based outside the United States.

Inception Date. The date on which the assets of a fund (or one of its share classes) are first invested in accordance with the fund’s investment objective. For funds with a subscription period, the inception date is the day after that period ends. Investment performance is measured from the inception date.

Median Market Cap. An indicator of the size of companies in which a fund invests; the midpoint of market capitalization (market price x shares outstanding) of a fund’s stocks, weighted by the proportion of the fund’s assets invested in each stock. Stocks representing half of the fund’s assets have market capitalizations above the median, and the rest are below it.

Price/Book Ratio. The share price of a stock divided by its net worth, or book value, per share. For a fund, the weighted average price/book ratio of the stocks it holds.

Price/Earnings Ratio. The ratio of a stock’s current price to its per-share earnings over the past year. For a fund, the weighted average P/E of the stocks it holds. P/E is an indicator of market expectations about corporate prospects; the higher the P/E, the greater the expectations for a company’s future growth.

R-Squared. A measure of how much of a fund’s past returns can be explained by the returns from the market in general, as measured by a given index. If a fund’s total returns were precisely synchronized with an index’s returns, its R-squared would be 1.00. If the fund’s returns bore no relationship to the index’s returns, its R-squared would be 0.

Return on Equity. The annual average rate of return generated by a company during the past five years for each dollar of shareholder’s equity (net income divided by shareholder’s equity). For a fund, the weighted average return on equity for the companies whose stocks it holds.

Short-Term Reserves. The percentage of a fund invested in highly liquid, short-term securities that can be readily converted to cash.

Turnover Rate. An indication of the fund’s trading activity. Funds with high turnover rates incur higher transaction costs and may be more likely to distribute capital gains (which may be taxable to investors). The turnover rate excludes in-kind transactions, which have minimal impact on costs.

Yield. A snapshot of a fund’s income from interest and dividends. The yield, expressed as a percentage of the fund’s net asset value, is based on income earned over the past 30 days and is annualized, or projected forward for the coming year. The index yield is based on the current annualized rate of income provided by securities in the index.

The People Who Govern Your Fund

The trustees of your mutual fund are there to see that the fund is operated and managed in your best interests since, as a shareholder, you are a part owner of the fund. Your fund’s trustees also serve on the board of directors of The Vanguard Group, Inc., which is owned by the Vanguard funds and provides services to them on an at-cost basis.

A majority of Vanguard’s board members are independent, meaning that they have no affiliation with Vanguard or the funds they oversee, apart from the sizable personal investments they have made as private individuals.

Our independent board members bring distinguished backgrounds in business, academia, and public service to their task of working with Vanguard officers to establish the policies and oversee the activities of the funds. Among board members’ responsibilities are selecting investment advisors for the funds; monitoring fund operations, performance, and costs; reviewing contracts; nominating and selecting new trustees/directors; and electing Vanguard officers.

Each trustee serves a fund until its termination; or until the trustee’s retirement, resignation, or death; or otherwise as specified in the fund’s organizational documents. Any trustee may be removed at a shareholders’ meeting by a vote representing two-thirds of the net asset value of all shares of the fund together with shares of other Vanguard funds organized within the same trust. The table on these two pages shows information for each trustee and executive officer of the fund. The mailing address of the trustees and officers is P.O. Box 876, Valley Forge, PA 19482.

Chairman’s Letter

Dear Shareholder,

Buoyed by healthy economic growth and low inflation, the broad U.S. stock market turned in a fourth straight year of positive performance in 2006. The Dow Jones Wilshire 5000 Composite Index gained 15.9%, with broad mid- and small-capitalization indexes also producing strong showings.

The Investor Shares of Vanguard Extended Market Index Fund and Vanguard Mid-Cap Index Fund gained 14.3% and 13.6%, respectively. Both funds fulfilled their objectives of closely tracking their target indexes. They also surpassed the average 12.2% gain among mid-cap core funds, as calculated by Lipper Inc.

Beginning in August, Vanguard added funds investing in the value and the growth slices of the mid-cap stock market. During the brief period since then, the value index outperformed its growth counterpart by a significant margin.

Strong second half pushed stocks to new high

Beginning in mid-July, stocks climbed steadily through the remainder of the year, with the Dow Jones Industrial Average setting a record high on December 27. Despite a soft housing sector and ongoing troubles within the U.S. auto industry, the economy continued to grow and corporate profits remained strong.

4

For the year, small-capitalization stocks beat out large-cap issues, and value stocks outperformed their growth-oriented counterparts. International stocks continued to best domestic equities, particularly in emerging markets and Europe. A declining dollar further enhanced returns abroad for U.S.-based investors.

Bond returns remained modest as the Fed paused its rate hikes

The Federal Reserve Board extended its money-tightening campaign during the first half of the year, raising its target for the federal funds rate four times. The Fed then paused, leaving the target rate unchanged at 5.25% for the rest of the year, and inflation fears eased. Bond yields declined in the second half of the year, and short-term yields were higher than longer-term yields.

Fixed income returns for 2006 were modest, with the broad taxable bond market returning 4.3% and municipal bonds providing 4.8%.

Dominance of financial stocks drove mid-cap performance

Within the universe of mid-cap stocks, financial issues have a strong influence on performance. The sector on average represented more than one-fifth of both the Extended Market and Mid-Cap Index Funds. For the year, the sector’s stellar gains contributed to the funds’ returns as banks, brokerage firms, asset managers, real estate investment trusts (REITs), and commodity stock exchanges turned in excellent showings.

Not only did these companies enjoy strong earnings, but they also benefited from an active market for mergers and

acquisitions. For example, CBOT Holdings, owner of the Chicago Board of Trade, rose 62% last year. The exchange hosts trading in derivatives contracts tied to commodities, interest rates, and currencies. Its performance reflected record volume in contracts and its acquisition by the Chicago Mercantile Exchange. Banks and REITs also were takeover candidates.

The stocks of utilities, materials, and telecommunication services companies rose more steeply than financials stocks; however, each represents a much smaller part of the mid-cap universe. The performance of all four sectors helps explain the persistence of the recent strength in value-oriented indexes and portfolios. Value managers favor stocks that pay dividends and that have lower

valuations (that is, their prices are less dear because expectations for earnings growth are more modest). Stocks with these characteristics are heavily represented among banks, utilities, and materials and telecommunication companies.

No sector turned in a negative performance; the weakest gains came from energy stocks and health care stocks. Oil prices fell during the year, hurting profits at companies that supply the energy industry. For example, Nabors Industries, the world’s largest land-based oil and gas driller, saw declining demand for its equipment as gas prices fell amid mild winter forecasts. Within health care, pharmaceutical firms were the weak spot.

Funds’ performance reflects indexing skill and low costs

In the table below, you can see that the two mid-cap funds with meaningful track records have been doing an excellent job of tracking their indexes. The feat is significant, given that indexes bear none of the costs that detract from a mutual fund’s return. The funds’ record reflects two competitive advantages: first, the expertise of Vanguard’s Quantitative Equity Group, which has developed proprietary index-tracking methodologies and trading strategies, and second, the funds’ historically low expense ratios.

The table shows the longer-term annualized returns for the two funds, as well as for their comparative measures. During the periods covered, the return of

The figures shown represent past performance, which is not a guarantee of future results. (Current performance may be lower or higher than the performance data cited. For performance data current to the most recent month-end, visit our website at www.vanguard.com.) Note, too, that both investment returns and principal value can fluctuate widely, so an investor’s shares, when sold, could be worth more or less than their original cost.

the Extended Market Index Fund lagged the average result for peer funds, while that of the Mid-Cap Index Fund was ahead by a significant margin. In 2005, the Extended Market Index Fund changed to a new target index; the former benchmark included a greater proportion of small-cap stocks than was typical for funds in the peer group. This factor had opened a performance gap, since small-caps did not keep up with larger stocks during most of the 1990s.

A powerful case for a simple strategy

Although indexing is a long-term strategy, with benefits that become especially clear over time, its virtues are often evident in the short run, too. The 2006 performance of Vanguard’s mid-cap index funds was particularly gratifying.

Still, it’s important to recognize that there will inevitably be years when your fund’s actively managed competitors outperform it. We understand that neither under- nor outperformance is all that meaningful in the short term, which is precisely why we always encourage investors to evaluate their portfolios from a long-term perspective.

We believe that our mid-cap index funds offer practical ways to capitalize on the long-term potential of this segment of the market. We encourage you to combine them with other funds to complete your exposure to stock and bond markets and investment approaches.

Thank you for entrusting your assets to Vanguard.

Sincerely,

John J. Brennan

Chairman and Chief Executive Officer

Extended Market Index Fund

Notes to Financial Statements

Vanguard Extended Market Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers five classes of shares: Investor Shares, Admiral Shares, Signal Shares, Institutional Shares, and ETF Shares. Investor Shares are available to any investor who meets the fund’s minimum purchase requirements. Admiral Shares are designed for investors who meet certain administrative, servicing, tenure, and account-size criteria. Signal Shares are designed for institutional investors who meet certain administrative, servicing, and account-size criteria. Signal Shares were first issued on September 1, 2006. Institutional Shares are designed for investors who meet certain administrative and servicing criteria and invest a minimum of $5 million. ETF Shares are listed for trading on the American Stock Exchange; they can be purchased and sold through a broker.

A. The following significant accounting policies conform to generally accepted accounting principles for U.S. mutual funds. The fund consistently follows such policies in preparing its financial statements.

1. Security Valuation: Securities are valued as of the close of trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the valuation date. Equity securities are valued at the latest quoted sales prices or official closing prices taken from the primary market in which each security trades; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Securities for which market quotations are not readily available, or whose values have been materially affected by events occurring before the fund’s pricing time but after the close of the securities’ primary markets, are valued by methods deemed by the board of trustees to represent fair value. Investments in Vanguard Market Liquidity Fund are valued at that fund’s net asset value. Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value.

2. Futures Contracts: The fund uses index futures contracts to a limited extent, with the objectives of maintaining full exposure to the stock market, enhancing returns, maintaining liquidity, and minimizing transaction costs. The fund may purchase futures contracts to immediately invest incoming cash in the market, or sell futures in response to cash outflows, thereby simulating a fully invested position in the underlying index while maintaining a cash balance for liquidity. The fund may seek to enhance returns by using futures contracts instead of the underlying securities when futures are believed to be priced more attractively than the underlying securities. The primary risks associated with the use of futures contracts are imperfect correlation between changes in market values of stocks held by the fund and the prices of futures contracts, and the possibility of an illiquid market.

Futures contracts are valued at their quoted daily settlement prices. The aggregate principal amounts of the contracts are not recorded in the Statement of Net Assets. Fluctuations in the value of the contracts are recorded in the Statement of Net Assets as an asset (liability) and in the Statement of Operations as unrealized appreciation (depreciation) until the contracts are closed, when they are recorded as realized futures gains (losses).

3. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its taxable income. Accordingly, no provision for federal income taxes is required in the financial statements.

4. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

25

Extended Market Index Fund

5. Security Lending: The fund may lend its securities to qualified institutional borrowers to earn additional income. Security loans are required to be secured at all times by collateral at least equal to the market value of securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability for the return of the collateral, during the period the securities are on loan. Security lending income represents the income earned on investing cash collateral, less expenses associated with the loan.

6. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold.

Each class of shares has equal rights as to assets and earnings, except that each class separately bears certain class-specific expenses related to maintenance of shareholder accounts (included in Management and Administrative expenses) and shareholder reporting. Marketing and distribution expenses are allocated to each class of shares based on a method approved by the board of trustees. Income, other non-class-specific expenses, and gains and losses on investments are allocated to each class of shares based on its relative net assets.

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At December 31, 2006, the fund had contributed capital of $1,260,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 1.26% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

C. Distributions are determined on a tax basis and may differ from net investment income and realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when certain items of income, expense, gain, or loss are recognized in different periods for financial statement and tax purposes; these differences will reverse at some time in the future. Differences in classification may also result from the treatment of short-term gains as ordinary income for tax purposes.

During the year ended December 31, 2006, the fund realized $785,997,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

For tax purposes, at December 31, 2006, the fund had $2,408,000 of ordinary income available for distribution. The fund had available realized losses of $160,782,000 to offset future net capital gains of $100,407,000 through December 31, 2011, and $60,375,000 through December 31, 2014.

At December 31, 2006, the cost of investment securities for tax purposes was $10,481,073,000. Net unrealized appreciation of investment securities for tax purposes was $2,755,772,000, consisting of unrealized gains of $3,786,063,000 on securities that had risen in value since their purchase and $1,030,291,000 in unrealized losses on securities that had fallen in value since their purchase.

Extended Market Index Fund

At December 31, 2006, the aggregate settlement value of open futures contracts expiring in March 2007 and the related unrealized appreciation (depreciation) were:

			($000)
		Aggregate	Unrealized
	Number of	Settlement	Appreciation
Futures Contracts	Long Contracts	Value	(Depreciation)
Russell 2000 Index	39	15,501	(39)
S&P MidCap 400 Index	32	12,981	(212)
E-mini Russell 2000 Index	115	9,141	(84)

Unrealized appreciation (depreciation) on open futures contracts is required to be treated as realized gain (loss) for tax purposes.

D. During the year ended December 31, 2006, the fund purchased $4,220,097,000 of investment securities and sold $3,371,410,000 of investment securities other than temporary cash investments.

E. The market value of securities on loan to broker-dealers at December 31, 2006, was $453,366,000, for which the fund received cash collateral of $489,603,000.

F. Capital share transactions for each class of shares were:

G. In June 2006, the Financial Accounting Standards Board issued Interpretation No. 48 (“FIN 48”), “Accounting for Uncertainty in Income Taxes.” FIN 48 establishes the minimum threshold for recognizing, and a system for measuring, the benefits of tax-return positions in financial statements. FIN 48 will be effective for the fund’s fiscal year ending December 31, 2007. Management is in the process of analyzing the fund’s tax positions for purposes of implementing FIN 48; based on the analysis completed to date, management does not believe the adoption of FIN 48 will result in any material impact to the fund’s financial statements.

Mid-Cap Index Fund

Notes to Financial Statements

Vanguard Mid-Cap Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers four classes of shares: Investor Shares, Admiral Shares, Institutional Shares, and ETF Shares. Investor Shares are available to any investor who meets the fund’s minimum purchase requirements. Admiral Shares are designed for investors who meet certain administrative, servicing, tenure, and account-size criteria. Institutional Shares are designed for investors who meet certain administrative and servicing criteria and invest a minimum of $5 million. ETF Shares are listed for trading on the American Stock Exchange; they can be purchased and sold through a broker.

A. The following significant accounting policies conform to generally accepted accounting principles for U.S. mutual funds. The fund consistently follows such policies in preparing its financial statements.

1 Security Valuation: Securities are valued as of the close of trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the valuation date. Equity securities are valued at the latest quoted sales prices or official closing prices taken from the primary market in which each security trades; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Securities for which market quotations are not readily available, or whose values have been materially affected by events occurring before the fund’s pricing time but after the close of the securities’ primary markets, are valued by methods deemed by the board of trustees to represent fair value. Investments in Vanguard Market Liquidity Fund are valued at that fund’s net asset value. Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value.

2. Futures Contracts: The fund uses index futures contracts to a limited extent, with the objectives of maintaining full exposure to the stock market, enhancing returns, maintaining liquidity, and minimizing transaction costs. The fund may purchase futures contracts to immediately invest incoming cash in the market, or sell futures in response to cash outflows, thereby simulating a fully invested position in the underlying index while maintaining a cash balance for liquidity. The fund may seek to enhance returns by using futures contracts instead of the underlying securities when futures are believed to be priced more attractively than the underlying securities. The primary risks associated with the use of futures contracts are imperfect correlation between changes in market values of stocks held by the fund and the prices of futures contracts, and the possibility of an illiquid market.

Futures contracts are valued at their quoted daily settlement prices. The aggregate principal amounts of the contracts are not recorded in the Statement of Net Assets. Fluctuations in the value of the contracts are recorded in the Statement of Net Assets as an asset (liability) and in the Statement of Operations as unrealized appreciation (depreciation) until the contracts are closed, when they are recorded as realized futures gains (losses).

3. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its taxable income. Accordingly, no provision for federal income taxes is required in the financial statements.

4. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

5. Security Lending: The fund may lend its securities to qualified institutional borrowers to earn additional income. Security loans are required to be secured at all times by collateral at least equal to the market value of securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability for the return of the collateral, during the period the securities are on loan. Security lending income represents the income earned on investing cash collateral, less expenses associated with the loan.

6. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold.

Each class of shares has equal rights as to assets and earnings, except that each class separately bears certain class-specific expenses related to maintenance of shareholder accounts (included in Management and Administrative expenses) and shareholder reporting. Marketing and distribution expenses are allocated to each class of shares based on a method approved by the board of trustees. Income, other non-class-specific expenses, and gains and losses on investments are allocated to each class of shares based on its relative net assets.

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At December 31, 2006, the fund had contributed capital of $1,767,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 1.77% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

C. Distributions are determined on a tax basis and may differ from net investment income and realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when certain items of income, expense, gain, or loss are recognized in different periods for financial statement and tax purposes; these differences will reverse at some time in the future. Differences in classification may also result from the treatment of short-term gains as ordinary income for tax purposes.

During the year ended December 31, 2006, the fund realized $959,445,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

For tax purposes, at December 31, 2006, the fund had $3,708,000 of ordinary income available for distribution. The fund had available realized losses of $169,094,000 to offset future net capital gains of $20,314,000 through December 31, 2011, $63,490,000 through December 31, 2014, and $85,290,000 through December 31, 2015.

At December 31, 2006, the cost of investment securities for tax purposes was $14,361,753,000. Net unrealized appreciation of investment securities for tax purposes was $3,793,542,000, consisting of unrealized gains of $4,058,424,000 on securities that had risen in value since their purchase and $264,882,000 in unrealized losses on securities that had fallen in value since their purchase.

At December 31, 2006, the aggregate settlement value of open futures contracts expiring in March 2007 and the related unrealized appreciation (depreciation) were:

	Number of	Settlement	Appreciation

Mid-Cap Index Fund

Unrealized appreciation (depreciation) on open futures contracts is required to be treated as realized gain (loss) for tax purposes.

D. During the year ended December 31, 2006, the fund purchased $8,091,471,000 of investment securities and sold $5,113,983,000 of investment securities other than temporary cash investments.

E. The market value of securities on loan to broker-dealers at December 31, 2006, was $182,114,000, for which the fund received cash collateral of $192,415,000.

G. In June 2006, the Financial Accounting Standards Board issued Interpretation No. 48 (“FIN 48”), “Accounting for Uncertainty in Income Taxes.” FIN 48 establishes the minimum threshold for recognizing, and a system for measuring, the benefits of tax-return positions in financial statements. FIN 48 will be effective for the fund’s fiscal year ending December 31, 2007. Management is in the process of analyzing the fund’s tax positions for purposes of implementing FIN 48; based on the analysis completed to date, management does not believe the adoption of FIN 48 will result in any material impact to the fund’s financial statements.

Mid-Cap Growth Index Fund

Notes to Financial Statements

Vanguard Mid-Cap Growth Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares: Investor Shares and ETF Shares. Investor Shares were first issued on August 24, 2006, and are available to any investor who meets the fund’s minimum purchase requirements. ETF Shares were first issued on August 17, 2006, and first offered to the public on August 24, 2006. ETF Shares are listed for trading on the American Stock Exchange; they can be purchased and sold through a broker.

A. The following significant accounting policies conform to generally accepted accounting principles for U.S. mutual funds. The fund consistently follows such policies in preparing its financial statements.

1 Security Valuation: Securities are valued as of the close of trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the valuation date. Equity securities are valued at the latest quoted sales prices or official closing prices taken from the primary market in which each security trades; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Securities for which market quotations are not readily available, or whose values have been materially affected by events occurring before the fund’s pricing time but after the close of the securities’ primary markets, are valued by methods deemed by the board of trustees to represent fair value. Investments in Vanguard Market Liquidity Fund are valued at that fund’s net asset value.

2. Federal Income Taxes: The fund intends to qualify as a regulated investment company and distribute all of its taxable income. Accordingly, no provision for federal income taxes is required in the financial statements.

3. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

4. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold.

Each class of shares has equal rights as to assets and earnings, except that each class separately bears certain class-specific expenses related to maintenance of shareholder accounts (included in Management and Administrative expenses) and shareholder reporting. Marketing and distribution expenses are allocated to each class of shares based on a method approved by the board of trustees. Income, other non-class-specific expenses, and gains and losses on investments are allocated to each class of shares based on its relative net assets.

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At December 31, 2006, the fund had contributed capital of $5,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.005% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

C. Distributions are determined on a tax basis and may differ from net investment income and realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when certain items of income, expense, gain, or loss are recognized in different periods for financial statement and tax purposes; these differences will reverse at some time in the future. Differences in classification may also result from the treatment of short-term gains as ordinary income for tax purposes.

58

Mid-Cap Growth Index Fund

During the period ended December 31, 2006, the fund realized $2,220,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

For tax purposes, at December 31, 2006, the fund had $12,000 of ordinary income available for distribution. The fund had available realized losses of $374,000 to offset future net capital gains of $35,000 through December 31, 2014, and $339,000 through December 31, 2015.

At December 31, 2006, the cost of investment securities for tax purposes was $45,771,000. Net unrealized appreciation of investment securities for tax purposes was $1,290,000, consisting of unrealized gains of $2,615,000 on securities that had risen in value since their purchase and $1,325,000 in unrealized losses on securities that had fallen in value since their purchase.

D. During the period ended December 31, 2006, the fund purchased $74,411,000 of investment securities and sold $31,064,000 of investment securities other than temporary cash investments.

E. Capital share transactions for each class of shares were:

	Inception1 to

Redeemed	(22,355)	(400)
Net Increase (Decrease)—ETF Shares	19,287	400

F. In June 2006, the Financial Accounting Standards Board issued Interpretation No. 48 (“FIN 48”), “Accounting for Uncertainty in Income Taxes.” FIN 48 establishes the minimum threshold for recognizing, and a system for measuring, the benefits of tax-return positions in financial statements. FIN 48 will be effective for the fund’s fiscal year ending December 31, 2007. Management is in the process of analyzing the fund’s tax positions for purposes of implementing FIN 48; based on the analysis completed to date, management does not believe the adoption of FIN 48 will result in any material impact to the fund’s financial statements.

1 Inception was August 24, 2006, for Investor Shares and August 17, 2006, for ETF Shares.

Mid-Cap Value Index Fund

Notes to Financial Statements

Vanguard Mid-Cap Value Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares: Investor Shares and ETF Shares. Investor Shares were first issued on August 24, 2006, and are available to any investor who meets the fund’s minimum purchase requirements. ETF Shares were first issued on August 17, 2006, and first offered to the public on August 24, 2006. ETF Shares are listed for trading on the American Stock Exchange; they can be purchased and sold through a broker.

A. The following significant accounting policies conform to generally accepted accounting principles for U.S. mutual funds. The fund consistently follows such policies in preparing its financial statements.

1. Security Valuation: Securities are valued as of the close of trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the valuation date. Equity securities are valued at the latest quoted sales prices or official closing prices taken from the primary market in which each security trades; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Securities for which market quotations are not readily available, or whose values have been materially affected by events occurring before the fund’s pricing time but after the close of the securities’ primary markets, are valued by methods deemed by the board of trustees to represent fair value. Investments in Vanguard Market Liquidity Fund are valued at that fund’s net asset value.

2. Federal Income Taxes: The fund intends to qualify as a regulated investment company and distribute all of its taxable income. Accordingly, no provision for federal income taxes is required in the financial statements.

3. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

4. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold.

Each class of shares has equal rights as to assets and earnings, except that each class separately bears certain class-specific expenses related to maintenance of shareholder accounts (included in Management and Administrative expenses) and shareholder reporting. Marketing and distribution expenses are allocated to each class of shares based on a method approved by the board of trustees. Income, other non-class-specific expenses, and gains and losses on investments are allocated to each class of shares based on its relative net assets.

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At December 31, 2006, the fund had contributed capital of $8,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.01% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

C. Distributions are determined on a tax basis and may differ from net investment income and realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when certain items of income, expense, gain, or loss are recognized in different periods for financial statement and tax purposes; these differences will reverse at some time in the future. Differences in classification may also result from the treatment of short-term gains as ordinary income for tax purposes.

71

Mid-Cap Value Index Fund

During the period ended December 31, 2006, the fund realized $1,896,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

For tax purposes, at December 31, 2006, the fund had $22,000 of ordinary income available for distribution. The fund had available realized losses of $52,000 to offset future net capital gains of $11,000 through December 31, 2014, and $41,000 through December 31, 2015.

At December 31, 2006, the cost of investment securities for tax purposes was $108,592,000. Net unrealized appreciation of investment securities for tax purposes was $4,406,000, consisting of unrealized gains of $5,029,000 on securities that had risen in value since their purchase and $623,000 in unrealized losses on securities that had fallen in value since their purchase.

D. During the period ended December 31, 2006, the fund purchased $135,971,000 of investment securities and sold $30,860,000 of investment securities other than temporary cash investments.

E. Capital share transactions for each class of shares were:

	Inception1 to
	December 31, 2006
	Amount	Shares
	($000)	(000)
Investor Shares
Issued	65,602	3,032

Redeemed	(2,673)	(122)
Net Increase (Decrease)—Investor Shares	63,244	2,924
ETF Shares

Issued in Lieu of Cash Distributions	—	—
Redeemed	(22,496)	(400)
Net Increase (Decrease)—ETF Shares	41,957	814

F. In June 2006, the Financial Accounting Standards Board issued Interpretation No. 48 (“FIN 48”), “Accounting for Uncertainty in Income Taxes.” FIN 48 establishes the minimum threshold for recognizing, and a system for measuring, the benefits of tax-return positions in financial statements. FIN 48 will be effective for the fund’s fiscal year ending December 31, 2007. Management is in the process of analyzing the fund’s tax positions for purposes of implementing FIN 48; based on the analysis completed to date, management does not believe the adoption of FIN 48 will result in any material impact to the fund’s financial statements.

1 Inception was August 24, 2006, for Investor Shares and August 17, 2006, for ETF Shares.

Report of Independent Registered Public Accounting Firm

To the Trustees of Vanguard Index Funds and Shareholders of Vanguard Extended Market Index Fund, Vanguard Mid-Cap Growth Index Fund, Vanguard Mid-Cap Value Index Fund, and Vanguard Mid-Cap Index Fund:

In our opinion, the accompanying statement of net assets—investments summary, statements of net assets, and statement of assets and liabilities and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Vanguard Extended Market Index Fund, Vanguard Mid-Cap Growth Index Fund, Vanguard Mid-Cap Value Index Fund, and Vanguard Mid-Cap Index Fund (separate funds of Vanguard Index Funds, hereafter referred to as the “Funds”) at December 31, 2006, the results of each of their operations, the changes in each of their net assets, and the financial highlights for each of the periods indicated, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Funds’ management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at December 31, 2006 by correspondence with the custodian and broker and by agreement to the underlying ownership records for Vanguard Market Liquidity Fund, provide a reasonable basis for our opinion.

Your Fund’s After-Tax Returns

This table presents returns both before and after taxes for those Mid-Capitalization Stock Index Funds that have at least one year of operating history. The after-tax returns are shown in two ways: (1) assuming that an investor owned the fund during the entire period and paid taxes on the fund’s distributions, and (2) assuming that an investor paid taxes on the fund’s distributions and sold all shares at the end of each period.

Calculations are based on the highest individual federal income tax and capital gains tax rates in effect at the times of the distributions and the hypothetical sales. State and local taxes were not considered. After-tax returns reflect any qualified dividend income. (In the example, returns after the sale of fund shares may be higher than those assuming no sale. This occurs when the sale would have produced a capital loss. The calculation assumes that the investor received a tax deduction for the loss.)

The table shows returns for Investor Shares only; returns for other share classes will differ. Please note that your actual after-tax returns will depend on your tax situation and may differ from those shown. Also note that if you own the fund in a tax-deferred account, such as an individual retirement account or a 401(k) plan, this information does not apply to you. Such accounts are not subject to current taxes.

Finally, keep in mind that a fund’s performance—whether before or after taxes—does not guarantee future results.

About Your Fund’s Expenses

As a shareholder of the fund, you incur ongoing costs, which include costs for portfolio management, administrative services, and shareholder reports (like this one), among others. Operating expenses, which are deducted from a fund’s gross income, directly reduce the investment return of the fund.

A fund’s expenses are expressed as a percentage of its average net assets. This figure is known as the expense ratio. The following examples, for the funds and share classes of funds that have at least six months of operating history, are intended to help you understand the ongoing costs (in dollars) of investing in your fund and to compare these costs with those of other mutual funds. The examples are based on an investment of $1,000 made at the beginning of the period shown and held for the entire period.

The tables on pages 76 and 77 illustrate your fund’s costs in two ways:

• Based on actual fund return. This section helps you to estimate the actual expenses that you paid over the period. The “Ending Account Value” shown is derived from the fund’s actual return, and the third column shows the dollar amount that would have been paid by an investor who started with $1,000 in the fund. You may use the information here, together with the amount you invested, to estimate the expenses that you paid over the period.

To do so, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number given for your fund under the heading “Expenses Paid During Period.”

• Based on hypothetical 5% yearly return. This section is intended to help you compare your fund’s costs with those of other mutual funds. It assumes that the fund had a yearly return of 5% before expenses, but that the expense ratio is unchanged. In this case—because the return used is not the fund’s actual return—the results do not apply to your investment. The example is useful in making comparisons because the Securities and Exchange Commission requires all mutual funds to calculate expenses based on a 5% return. You can assess your fund’s costs by comparing this hypothetical example with the hypothetical examples that appear in shareholder reports of other funds.

Institutional Shares	1,000.00	1,084.18	0.32
ETF Shares	1,000.00	1,084.27	0.42

1 The calculations are based on expenses incurred in the most recent six-month period.The funds’ annualized six-month expense ratios for that period are: 0.24% for the Extended Market Index Fund Investor Shares, 0.10% for Admiral Shares, 0.06% for Institutional Shares, and 0.08% for ETF Shares; 0.21% for the Mid-Cap Index Fund Investor Shares, 0.12% for Admiral Shares, 0.07% for Institutional Shares, and 0.12% for ETF Shares. The dollar amounts shown as “Expenses Paid” are equal to the annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent six-month period, then divided by the number of days in the most recent 12-month period.

Note that the expenses shown in the table above are meant to highlight and help you compare ongoing costs only and do not reflect any transactional costs or account maintenance fees. They do not include your fund’s low-balance fee, which is described in the prospectus. If this fee were applied to your account, your costs would be higher. Your fund does not charge transaction fees, such as purchase or redemption fees, nor does it carry a “sales load.”

The calculations assume no shares were bought or sold during the period. Your actual costs may have been higher or lower, depending on the amount of your investment and the timing of any purchases or redemptions.

You can find more information about the fund’s expenses, including annual expense ratios, in the Financial Statements section of this report. For additional information on operating expenses and other shareholder costs, please refer to the appropriate fund prospectus.

1 The calculations are based on expenses incurred in the most recent six-month period.The funds’ annualized six-month expense ratios for that period are: 0.24% for the Extended Market Index Fund Investor Shares, 0.10% for Admiral Shares, 0.06% for Institutional Shares, and 0.08% for ETF Shares; 0.21% for the Mid-Cap Index Fund Investor Shares, 0.12% for Admiral Shares, 0.07% for Institutional Shares, and 0.12% for ETF Shares. The dollar amounts shown as “Expenses Paid” are equal to the annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent six-month period, then divided by the number of days in the most recent 12-month period.

Glossary

Beta. A measure of the magnitude of a fund’s past share-price fluctuations in relation to the ups and downs of a given market index. The index is assigned a beta of 1.00. Compared with a given index, a fund with a beta of 1.20 typically would have seen its share price rise or fall by 12% when the index rose or fell by 10%. A fund’s beta should be reviewed in conjunction with its R-squared (see definition below). The lower the R-squared, the less correlation there is between the fund and the index, and the less reliable beta is as an indicator of volatility.

Earnings Growth Rate. The average annual rate of growth in earnings over the past five years for the stocks now in a fund.

Expense Ratio. The percentage of a fund’s average net assets used to pay its annual administrative and advisory expenses. These expenses directly reduce returns to investors.

Foreign Holdings. The percentage of a fund represented by stocks or depositary receipts of companies based outside the United States.

Inception Date. The date on which the assets of a fund (or one of its share classes) are first invested in accordance with the fund’s investment objective. For funds with a subscription period, the inception date is the day after that period ends. Investment performance is measured from the inception date.

Median Market Cap. An indicator of the size of companies in which a fund invests; the midpoint of market capitalization (market price x shares outstanding) of a fund’s stocks, weighted by the proportion of the fund’s assets invested in each stock. Stocks representing half of the fund’s assets have market capitalizations above the median, and the rest are below it.

Price/Book Ratio. The share price of a stock divided by its net worth, or book value, per share. For a fund, the weighted average price/book ratio of the stocks it holds.

Price/Earnings Ratio. The ratio of a stock’s current price to its per-share earnings over the past year. For a fund, the weighted average P/E of the stocks it holds. P/E is an indicator of market expectations about corporate prospects; the higher the P/E, the greater the expectations for a company’s future growth.

R-Squared. A measure of how much of a fund’s past returns can be explained by the returns from the market in general, as measured by a given index. If a fund’s total returns were precisely synchronized with an index’s returns, its R-squared would be 1.00. If the fund’s returns bore no relationship to the index’s returns, its R-squared would be 0.

Return on Equity. The annual average rate of return generated by a company during the past five years for each dollar of shareholder’s equity (net income divided by shareholder’s equity). For a fund, the weighted average return on equity for the companies whose stocks it holds.

Short-Term Reserves. The percentage of a fund invested in highly liquid, short-term securities that can be readily converted to cash.

Turnover Rate. An indication of the fund’s trading activity. Funds with high turnover rates incur higher transaction costs and may be more likely to distribute capital gains (which may be taxable to investors). The turnover rate excludes in-kind transactions, which have minimal impact on costs.

Yield. A snapshot of a fund’s income from interest and dividends. The yield, expressed as a percentage of the fund’s net asset value, is based on income earned over the past 30 days and is annualized, or projected forward for the coming year. The index yield is based on the current annualized rate of income provided by securities in the index.

The People Who Govern Your Fund

The trustees of your mutual fund are there to see that the fund is operated and managed in your best interests since, as a shareholder, you are a part owner of the fund. Your fund’s trustees also serve on the board of directors of The Vanguard Group, Inc., which is owned by the Vanguard funds and provides services to them on an at-cost basis.

A majority of Vanguard’s board members are independent, meaning that they have no affiliation with Vanguard or the funds they oversee, apart from the sizable personal investments they have made as private individuals.

Our independent board members bring distinguished backgrounds in business, academia, and public service to their task of working with Vanguard officers to establish the policies and oversee the activities of the funds. Among board members’ responsibilities are selecting investment advisors for the funds; monitoring fund operations, performance, and costs; reviewing contracts; nominating and selecting new trustees/directors; and electing Vanguard officers.

Each trustee serves a fund until its termination; or until the trustee’s retirement, resignation, or death; or otherwise as specified in the fund’s organizational documents. Any trustee may be removed at a shareholders’ meeting by a vote representing two-thirds of the net asset value of all shares of the fund together with shares of other Vanguard funds organized within the same trust. The table on these two pages shows information for each trustee and executive officer of the fund. The mailing address of the trustees and officers is P.O. Box 876, Valley Forge, PA 19482.

Chairman’s Letter

Dear Shareholder,

Spurred by strong fourth-quarter gains, the U.S. stock market finished 2006 with a flourish. The Morgan Stanley Capital International (MSCI) US Broad Market Index returned a robust 15.7% for the year.

For the fiscal year ended December 31, 2006, Vanguard’s four large-capitalization stock index funds recorded solid—and in the case of Vanguard Value Index Fund, excellent—returns. All four funds tracked their target indexes closely, consistent with their objectives, and all four topped the average returns for their actively managed peers.

For taxable investors, it’s worth noting that the benefits of holding index funds can be even greater than those of investing in actively managed funds, as index funds’ low turnover and Vanguard’s disciplined management generally limit the distribution of realized capital gains. During 2006, none of these large-cap index funds distributed a capital gain.

Strong second half pushed stocks to new high

Beginning in mid-July, stocks climbed steadily through the remainder of the year, with the Dow Jones Industrial Average setting a record high on December 27. Despite a soft housing sector and ongoing troubles within the U.S. auto industry, the economy continued to grow and corporate profits remained strong.

4

For the year, small-cap stocks beat out large-cap issues, and value stocks outperformed their growth-oriented counterparts. International stocks continued to best domestic equities, particularly in emerging markets and Europe. A declining dollar further enhanced returns abroad for U.S.-based investors.

Bond returns remained modest as the Fed paused its rate hikes

The Federal Reserve Board extended its money-tightening campaign during the first half of the year, raising its target for the federal funds rate four times. The Fed then paused, leaving the target rate unchanged at 5.25% for the rest of the year, and inflation fears eased. Bond yields declined in the second half of the year, and short-term yields were higher than longer-term yields.

Fixed income returns for 2006 were modest, with the broad taxable bond market returning 4.3% and municipal bonds providing 4.8%.

Large-cap value stocks continued their outperformance

A robust fourth quarter brought the 2006 stock market to a close with healthy gains. The four Vanguard large-capitalization stock index funds performed strongly, with gains ranging from 9.0% for the Growth Index Fund to 22.1% for the Value Index Fund. The broader-based Large-Cap and Total Stock Market Index Funds, which hold both growth and value stocks, each posted a return of 15.5%—all figures are for the funds’ Investor Shares.

The Value Index Fund’s return reflected its comparatively heavy exposure to the energy and financials sectors, which performed well in 2006. On the other hand, the Growth Index Fund’s relatively heavy weightings in health care and technology stocks curbed its performance These two sectors, together accounting for about 45% of the Growth Index Fund’s average assets, lagged the overall market significantly

Still, it’s worth noting that the performance difference between these two funds—and between growth and value equities in general—narrows

considerably over longer time periods, as you can see in the ten-year performance chart below.

The Large-Cap Index Fund, which tracks the MSCI US Prime Market 750 Index, essentially combines the holdings of the Growth and Value Index Funds. The 15.5% gain of the Large-Cap Index Fund’s Investor Shares is roughly at the midpoint between the performances of these two funds—no surprise given the nature of the Large-Cap Index Fund’s holdings.

As for the Total Stock Market Index Fund, its one-year return of 15.5% for Investor Shares reflected the fund’s exposure to the entire market, including the strong relative performance of mid-cap stocks. Among the fund’s holdings, the rallying energy and financials sectors contributed most significantly to the fund’s performance.

As you can see in the table below, over the long term, indexing has proven its value. During the ten years ended

December 31, 2006, a hypothetical $10,000 investment in the Total Stock Market Index Fund’s Investor Shares would have grown to $22,763. The same investment in the average multi-cap core fund would have earned about $1,300 less. During the period, the Growth, Value, and Large-Cap Index Funds also outperformed their peer-group averages.

The reasons for these funds’ long-term success are numerous. Vanguard Quantitative Equity Group, the funds’ advisor, has proven to be exceptionally adept at closely tracking fund benchmarks. Also, because the large-cap index funds are broadly diversified, they’re less vulnerable to the risk that a few poorly performing stocks will significantly derail their performance. And because index funds, unlike many actively managed funds, remain fully invested, performance doesn’t suffer from the drag that uninvested cash can cause in a stock market that has risen over the long term.

Finally, there is the matter of costs. Vanguard index funds have exceptionally low operating and transaction costs, an advantage that compounds over time. For a comparison of expense ratios, please see page 6.

Indexing is a proven strategy

Although indexing is a long-term strategy, with benefits that become especially clear over time, its virtues are often evident in the short run, too. In fact, in 2006, all of the Vanguard large-cap index funds outpaced the average returns of their peer groups.

While our Large-Cap Index Funds’ 12-month performance is gratifying, it’s important to recognize that there will be years when the funds’ actively managed competitors outperform. In these missives, we routinely stress to investors that neither under- nor outperformance in the short term is all that meaningful. On the contrary, we always encourage our shareholders to evaluate their investments from a long-term perspective. Through the years, we have steadfastly counseled investors to stick with a carefully considered, balanced portfolio of stock, bond, and money market mutual funds suited to their unique circumstances.

As an investor, an important strategy for weathering the market’s uncertainties over the long term is to maintain a well-planned strategy. Investing in Vanguard’s large-cap stock index funds is a smart way to capitalize on the stock market’s long-term potential.

Thank you for investing with Vanguard.

Sincerely,

John J. Brennan

Chairman and Chief Executive Officer

Growth Index Fund

Notes to Financial Statements

Vanguard Growth Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers four classes of shares: Investor Shares, Admiral Shares, Institutional Shares, and ETF Shares. Investor Shares are available to any investor who meets the fund’s minimum purchase requirements. Admiral Shares are designed for investors who meet certain administrative, servicing, tenure, and account-size criteria. Institutional Shares are designed for investors who meet certain administrative and servicing criteria and invest a minimum of $5 million. ETF Shares are listed for trading on the American Stock Exchange; they can be purchased and sold through a broker.

A. The following significant accounting policies conform to generally accepted accounting principles for U.S. mutual funds. The fund consistently follows such policies in preparing its financial statements.

1. Security Valuation: Securities are valued as of the close of trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the valuation date. Equity securities are valued at the latest quoted sales prices or official closing prices taken from the primary market in which each security trades; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Securities for which market quotations are not readily available, or whose values have been materially affected by events occurring before the fund’s pricing time but after the close of the securities’ primary markets, are valued by methods deemed by the board of trustees to represent fair value. Investments in Vanguard Market Liquidity Fund are valued at that fund's net asset value.

2. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its taxable income. Accordingly, no provision for federal income taxes is required in the financial statements.

3. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

4. Security Lending: The fund may lend its securities to qualified institutional borrowers to earn additional income. Security loans are required to be secured at all times by collateral at least equal to the market value of securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability for the return of the collateral, during the period the securities are on loan. Security lending income represents the income earned on investing cash collateral, less expenses associated with the loan.

5. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold.

Each class of shares has equal rights as to assets and earnings, except that each class separately bears certain class-specific expenses related to maintenance of shareholder accounts (included in Management and Administrative expenses) and shareholder reporting. Marketing and distribution

26

Growth Index Fund

expenses are allocated to each class of shares based on a method approved by the board of trustees. Income, other non-class-specific expenses, and gains and losses on investments are allocated to each class of shares based on its relative net assets.

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At December 31, 2006, the fund had contributed capital of $1,229,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 1.23% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

C. Distributions are determined on a tax basis and may differ from net investment income and realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when certain items of income, expense, gain, or loss are recognized in different periods for financial statement and tax purposes; these differences will reverse at some time in the future. Differences in classification may also result from the treatment of short-term gains as ordinary income for tax purposes.

During the year ended December 31, 2006, the fund realized $12,554,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

For tax purposes, at December 31, 2006, the fund had $1,072,000 of ordinary income available for distribution. The fund had available realized losses of $3,464,458,000 to offset future net capital gains of $221,842,000 through December 31, 2008, $1,752,289,000 through December 31, 2009, $747,930,000 through December 31, 2010, and $742,397,000 through December 31, 2011.

At December 31, 2006, the cost of investment securities for tax purposes was $8,982,004,000. Net unrealized appreciation of investment securities for tax purposes was $3,751,768,000, consisting of unrealized gains of $3,968,536,000 on securities that had risen in value since their purchase and $216,768,000 in unrealized losses on securities that had fallen in value since their purchase.

D. During the year ended December 31, 2006, the fund purchased $4,392,303,000 of investment securities and sold $3,215,771,000 of investment securities, other than temporary cash investments.

E. The market value of securities on loan to broker-dealers at December 31, 2006, was $38,561,000, for which the fund received cash collateral of $40,608,000.

G. In June 2006, the Financial Accounting Standards Board issued Interpretation No. 48 (“FIN 48”), “Accounting for Uncertainty in Income Taxes.” FIN 48 establishes the minimum threshold for recognizing, and a system for measuring, the benefits of tax-return positions in financial statements. FIN 48 will be effective for the fund’s fiscal year ending December 31, 2007. Management is in the process of analyzing the fund’s tax positions for purposes of implementing FIN 48; based on the analysis completed to date, management does not believe the adoption of FIN 48 will result in any material impact to the fund’s financial statements.

Performance Summary

All of the returns in this report represent past performance, which is not a guarantee of future results that may be achieved by the fund. (Current performance may be lower or higher than the performance data cited. For performance data current to the most recent month-end, visit our website at www.vanguard.com.) Note, too, that both investment returns and principal value can fluctuate widely, so an investor’s shares, when sold, could be worth more or less than their original cost.

Value Index Fund

Notes to Financial Statements

Vanguard Value Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers four classes of shares: Investor Shares, Admiral Shares, Institutional Shares, and ETF Shares. Investor Shares are available to any investor who meets the fund’s minimum purchase requirements. Admiral Shares are designed for investors who meet certain administrative, servicing, tenure, and account-size criteria. Institutional Shares are designed for investors who meet certain administrative and servicing criteria and invest a minimum of $5 million. ETF Shares are listed for trading on the American Stock Exchange; they can be purchased and sold through a broker.

A. The following significant accounting policies conform to generally accepted accounting principles for U.S. mutual funds. The fund consistently follows such policies in preparing its financial statements.

1. Security Valuation: Securities are valued as of the close of trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the valuation date. Equity securities are valued at the latest quoted sales prices or official closing prices taken from the primary market in which each security trades; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Securities for which market quotations are not readily available, or whose values have been materially affected by events occurring before the fund’s pricing time but after the close of the securities’ primary markets, are valued by methods deemed by the board of trustees to represent fair value. Investments in Vanguard Market Liquidity Fund are valued at that fund’s net asset value.

2. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its taxable income. Accordingly, no provision for federal income taxes is required in the financial statements.

3. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

4. Security Lending: The fund may lend its securities to qualified institutional borrowers to earn additional income. Security loans are required to be secured at all times by collateral at least equal to the market value of securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability for the return of the collateral, during the period the securities are on loan. Security lending income represents the income earned on investing cash collateral, less expenses associated with the loan.

5. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold.

Each class of shares has equal rights as to assets and earnings, except that each class separately bears certain class-specific expenses related to maintenance of shareholder accounts (included in Management and Administrative expenses) and shareholder reporting. Marketing and distribution

44

Value Index Fund

expenses are allocated to each class of shares based on a method approved by the board of trustees. Income, other non-class-specific expenses, and gains and losses on investments are allocated to each class of shares based on its relative net assets.

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At December 31, 2006, the fund had contributed capital of $1,020,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 1.02% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

C. Distributions are determined on a tax basis and may differ from net investment income and realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when certain items of income, expense, gain, or loss are recognized in different periods for financial statement and tax purposes; these differences will reverse at some time in the future. Differences in classification may also result from the treatment of short-term gains as ordinary income for tax purposes.

During the year ended December 31, 2006, the fund realized $460,994,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

For tax purposes, at December 31, 2006, the fund had $1,622,000 of ordinary income available for distribution. The fund had available realized losses of $757,542,000 to offset future net capital gains of $125,066,000 through December 31, 2010, $503,996,000 through December 31, 2011, $40,920,000 through December 31, 2014, and $87,560,000 through December 31, 2015.

At December 31, 2006, the cost of investment securities for tax purposes was $8,643,828,000. Net unrealized appreciation of investment securities for tax purposes was $2,289,189,000, consisting of unrealized gains of $2,372,722,000 on securities that had risen in value since their purchase and $83,533,000 in unrealized losses on securities that had fallen in value since their purchase.

D. During the year ended December 31, 2006, the fund purchased $5,125,810,000 of investment securities and sold $2,852,098,000 of investment securities, other than temporary cash investments.

E. The market value of securities on loan to broker-dealers at December 31, 2006, was $10,281,000, for which the fund received cash collateral of $10,666,000.

G. In June 2006, the Financial Accounting Standards Board issued Interpretation No. 48 (“FIN 48”), “Accounting for Uncertainty in Income Taxes.” FIN 48 establishes the minimum threshold for recognizing, and a system for measuring, the benefits of tax-return positions in financial statements. FIN 48 will be effective for the fund’s fiscal year ending December 31, 2007. Management is in the process of analyzing the fund’s tax positions for purposes of implementing FIN 48; based on the analysis completed to date, management does not believe the adoption of FIN 48 will result in any material impact to the fund’s financial statements.

Large-Cap Index Fund

Notes to Financial Statements

Vanguard Large-Cap Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers four classes of shares: Investor Shares, Admiral Shares, Institutional Shares, and ETF Shares. Investor Shares are available to any investor who meets the fund’s minimum purchase requirements. Admiral Shares are designed for investors who meet certain administrative, servicing, tenure, and account-size criteria. Institutional Shares are designed for investors who meet certain administrative and servicing criteria and invest a minimum of $5 million. ETF Shares are listed for trading on the American Stock Exchange; they can be purchased and sold through a broker.

A. The following significant accounting policies conform to generally accepted accounting principles for U.S. mutual funds. The fund consistently follows such policies in preparing its financial statements.

1. Security Valuation: Securities are valued as of the close of trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the valuation date. Equity securities are valued at the latest quoted sales prices or official closing prices taken from the primary market in which each security trades; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Securities for which market quotations are not readily available, or whose values have been materially affected by events occurring before the fund’s pricing time but after the close of the securities’ primary markets, are valued by methods deemed by the board of trustees to represent fair value. Investments in Vanguard Market Liquidity Fund are valued at that fund’s net asset value. Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value.

2. Futures Contracts: The fund uses index futures contracts to a limited extent, with the objectives of maintaining full exposure to the stock market, enhancing returns, maintaining liquidity, and minimizing transaction costs. The fund may purchase futures contracts to immediately invest incoming cash in the market, or sell futures in response to cash outflows, thereby simulating a fully invested position in the underlying index while maintaining a cash balance for liquidity. The fund may seek to enhance returns by using futures contracts instead of the underlying securities when futures are believed to be priced more attractively than the underlying securities. The primary risks associated with the use of futures contracts are imperfect correlation between changes in market values of stocks held by the fund and the prices of futures contracts, and the possibility of an illiquid market.

Futures contracts are valued at their quoted daily settlement prices. The aggregate principal amounts of the contracts are not recorded in the Statement of Net Assets. Fluctuations in the value of the contracts are recorded in the Statement of Net Assets as an asset (liability) and in the Statement of Operations as unrealized appreciation (depreciation) until the contracts are closed, when they are recorded as realized futures gains (losses).

3. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its taxable income. Accordingly, no provision for federal income taxes is required in the financial statements.

4. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

56

Large-Cap Index Fund

5. Security Lending: The fund may lend its securities to qualified institutional borrowers to earn additional income. Security loans are required to be secured at all times by collateral at least equal to the market value of securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability for the return of the collateral, during the period the securities are on loan. Security lending income represents the income earned on investing cash collateral, less expenses associated with the loan.

6. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold.

Each class of shares has equal rights as to assets and earnings, except that each class separately bears certain class-specific expenses related to maintenance of shareholder accounts (included in Management and Administrative expenses) and shareholder reporting. Marketing and distribution expenses are allocated to each class of shares based on a method approved by the board of trustees. Income, other non-class-specific expenses, and gains and losses on investments are allocated to each class of shares based on its relative net assets.

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At December 31, 2006, the fund had contributed capital of $96,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.10% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

C. Distributions are determined on a tax basis and may differ from net investment income and realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when certain items of income, expense, gain, or loss are recognized in different periods for financial statement and tax purposes; these differences will reverse at some time in the future. Differences in classification may also result from the treatment of short-term gains as ordinary income for tax purposes.

During the year ended December 31, 2006, the fund realized $70,941,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

For tax purposes, at December 31, 2006, the fund had $147,000 of ordinary income available for distribution. The fund had available realized losses of $1,328,000 to offset future net capital gains of $11,000 through December 31, 2013, $463,000 through December 31, 2014, and $854,000 through December 31, 2015.

At December 31, 2006, the cost of investment securities for tax purposes was $987,965,000. Net unrealized appreciation of investment securities for tax purposes was $52,966,000, consisting of unrealized gains of $71,630,000 on securities that had risen in value since their purchase and $18,664,000 in unrealized losses on securities that had fallen in value since their purchase.

At December 31, 2006, the aggregate settlement value of open futures contracts expiring in March 2007 and the related unrealized appreciation (depreciation) were:

			($000)
	Number	Aggregate	Unrealized
	of Long	Settlement	Appreciation
Futures Contracts	Contracts	Value	(Depreciation)
S&P 500 Index	13	4,642	33

Unrealized appreciation (depreciation) on open futures contracts is required to be treated as realized gain (loss) for tax purposes.

D. During the year ended December 31, 2006, the fund purchased $899,994,000 of investment securities and sold $396,913,000 of investment securities, other than temporary cash investments.

E. The market value of securities on loan to broker-dealers at December 31, 2006, was $562,000, for which the fund received cash collateral of $599,000.

F. Capital share transactions for each class of shares were:

G. In June 2006, the Financial Accounting Standards Board issued Interpretation No. 48 (“FIN 48”), “Accounting for Uncertainty in Income Taxes.” FIN 48 establishes the minimum threshold for recognizing, and a system for measuring, the benefits of tax-return positions in financial statements. FIN 48 will be effective for the fund’s fiscal year ending December 31, 2007. Management is in the process of analyzing the fund’s tax positions for purposes of implementing FIN 48; based on the analysis completed to date, management does not believe the adoption of FIN 48 will result in any material impact to the fund’s financial statements.

Total Stock Market Index Fund

Notes to Financial Statements

Vanguard Total Stock Market Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers five classes of shares: Investor Shares, Admiral Shares, Signal Shares, Institutional Shares, and ETF Shares. Investor Shares are available to any investor who meets the fund’s minimum purchase requirements. Admiral Shares are designed for investors who meet certain administrative, servicing, tenure, and account-size criteria. Signal Shares are designed for institutional investors who meet certain administrative, servicing, and account-size criteria. Signal Shares were first issued on September 1, 2006. Institutional Shares are designed for investors who meet certain administrative and servicing criteria and invest a minimum of $5 million. ETF Shares are listed for trading on the American Stock Exchange; they can be purchased and sold through a broker.

A. The following significant accounting policies conform to generally accepted accounting principles for U.S. mutual funds. The fund consistently follows such policies in preparing its financial statements.

1. Security Valuation: Securities are valued as of the close of trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the valuation date. Equity securities are valued at the latest quoted sales prices or official closing prices taken from the primary market in which each security trades; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Securities for which market quotations are not readily available, or whose values have been materially affected by events occurring before the fund’s pricing time but after the close of the securities’ primary markets, are valued by methods deemed by the board of trustees to represent fair value. Investments in Vanguard Market Liquidity Fund are valued at that fund’s net asset value. Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value.

2. Futures Contracts: The fund uses index futures contracts to a limited extent, with the objectives of maintaining full exposure to the stock market, enhancing returns, maintaining liquidity, and minimizing transaction costs. The fund may purchase futures contracts to immediately invest incoming cash in the market, or sell futures in response to cash outflows, thereby simulating a fully invested position in the underlying index while maintaining a cash balance for liquidity. The fund may seek to enhance returns by using futures contracts instead of the underlying securities when futures are believed to be priced more attractively than the underlying securities. The primary risks associated with the use of futures contracts are imperfect correlation between changes in market values of stocks held by the fund and the prices of futures contracts, and the possibility of an illiquid market.

Futures contracts are valued at their quoted daily settlement prices. The aggregate principal amounts of the contracts are not recorded in the Statement of Net Assets. Fluctuations in the value of the contracts are recorded in the Statement of Net Assets as an asset (liability) and in the Statement of Operations as unrealized appreciation (depreciation) until the contracts are closed, when they are recorded as realized futures gains (losses).

3. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its taxable income. Accordingly, no provision for federal income taxes is required in the financial statements.

4. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

5. Security Lending: The fund may lend its securities to qualified institutional borrowers to earn additional income. Security loans are required to be secured at all times by collateral at least equal to the market value of securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability for the return of the collateral, during the period the securities are on loan. Security lending income represents the income earned on investing cash collateral, less expenses associated with the loan.

6. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold.

Each class of shares has equal rights as to assets and earnings, except that each class separately bears certain class-specific expenses related to maintenance of shareholder accounts (included in Management and Administrative expenses) and shareholder reporting. Marketing and distribution expenses are allocated to each class of shares based on a method approved by the board of trustees. Income, other non-class-specific expenses, and gains and losses on investments are allocated to each class of shares based on its relative net assets.

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At December 31, 2006, the fund had contributed capital of $8,209,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 8.21% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

C. Distributions are determined on a tax basis and may differ from net investment income and realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when certain items of income, expense, gain, or loss are recognized in different periods for financial statement and tax purposes; these differences will reverse at some time in the future. Differences in classification may also result from the treatment of short-term gains as ordinary income for tax purposes.

During the year ended December 31, 2006, the fund realized $1,066,131,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

For tax purposes, at December 31, 2006, the fund had $12,556,000 of ordinary income available for distribution. The fund had available realized losses of $1,908,675,000 to offset future net capital gains of $60,790,000 through December 31, 2009, $439,204,000 through December 31, 2010, $411,583,000 through December 31, 2011, $762,181,000 through December 31, 2013, and $234,917,000 through December 31, 2015.

Total Stock Market Index Fund

At December 31, 2006, the cost of investment securities for tax purposes was $66,818,113,000. Net unrealized appreciation of investment securities for tax purposes was $19,429,750,000, consisting of unrealized gains of $22,027,826,000 on securities that had risen in value since their purchase and $2,598,076,000 in unrealized losses on securities that had fallen in value since their purchase.

At December 31, 2006, the aggregate settlement value of open futures contracts expiring in March 2007 and the unrealized appreciation (depreciation) were:

			($000)
	Number	Aggregate	Unrealized
	of Long	Settlement	Appreciation
Futures Contracts	Contracts	Value	(Depreciation)
S&P 500 Index	1,000	357,100	1,754
E-mini S&P 500 Index	871	62,207	51
S&P MidCap 400 Index	79	32,046	(524)
Russell 2000 Index	24	9,539	(50)

Unrealized appreciation (depreciation) on open futures contracts is required to be treated as realized gain (loss) for tax purposes.

D. During the year ended December 31, 2006, the fund purchased $15,093,392,000 of investment securities and sold $4,668,797,000 of investment securities, other than temporary cash investments.

E. The market value of securities on loan to broker-dealers at December 31, 2006, was $595,504,000, for which the fund received cash collateral of $641,250,000.

G. In June 2006, the Financial Accounting Standards Board issued Interpretation No. 48 (“FIN 48”), “Accounting for Uncertainty in Income Taxes.” FIN 48 establishes the minimum threshold for recognizing, and a system for measuring, the benefits of tax-return positions in financial statements. FIN 48 will be effective for the fund’s fiscal year ending December 31, 2007. Management is in the process of analyzing the fund’s tax positions for purposes of implementing FIN 48; based on the analysis completed to date, management does not believe the adoption of FIN 48 will result in any material impact to the fund’s financial statements.

Your Fund’s After-Tax Returns

This table presents returns for your fund both before and after taxes. The after-tax returns are shown in two ways: (1) assuming that an investor owned the fund during the entire period and paid taxes on the fund’s distributions, and (2) assuming that an investor paid taxes on the fund’s distributions and sold all shares at the end of each period.

Calculations are based on the highest individual federal income tax and capital gains tax rates in effect at the times of the distributions and the hypothetical sales. State and local taxes were not considered. After-tax returns reflect any qualified dividend income. (In the example, returns after the sale of fund shares may be higher than those assuming no sale. This occurs when the sale would have produced a capital loss. The calculation assumes that the investor received a tax deduction for the loss.)

The table shows returns for Investor Shares only; returns for other share classes will differ. Please note that your actual after-tax returns will depend on your tax situation and may differ from those shown. Also note that if you own the fund in a tax-deferred account, such as an individual retirement account or a 401(k) plan, this information does not apply to you. Such accounts are not subject to current taxes.

Finally, keep in mind that a fund’s performance—whether before or after taxes—does not guarantee future results.

About Your Fund’s Expenses

As a shareholder of the fund, you incur ongoing costs, which include costs for portfolio management, administrative services, and shareholder reports (like this one), among others. Operating expenses, which are deducted from a fund’s gross income, directly reduce the investment return of the fund.

A fund’s expenses are expressed as a percentage of its average net assets. This figure is known as the expense ratio. The following examples are intended to help you understand the ongoing costs (in dollars) of investing in your fund and to compare these costs with those of other mutual funds. The examples are based on an investment of $1,000 made at the beginning of the period shown and held for the entire period.

The tables illustrate your fund’s costs in two ways:

• Based on actual fund return. This section helps you to estimate the actual expenses that you paid over the period. The “Ending Account Value” shown is derived from the fund’s actual return, and the third column shows the dollar amount that would have been paid by an investor who started with $1,000 in the fund. You may use the information here, together with the amount you invested, to estimate the expenses that you paid over the period.

To do so, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number given for your fund under the heading “Expenses Paid During Period.”

• Based on hypothetical 5% yearly return. This section is intended to help you compare your fund’s costs with those of other mutual funds. It assumes that the fund had a yearly return of 5% before expenses, but that the expense ratio is unchanged. In this case—because the return used is not the fund’s actual return—the results do not apply to your investment. The example is useful in making comparisons because the Securities and Exchange Commission requires all mutual funds to calculate expenses based on a 5% return. You can assess your fund’s costs by comparing this hypothetical example with the hypothetical examples that appear in shareholder reports of other funds.

Note that the expenses shown in the tables are meant to highlight and help you compare ongoing costs only and do not reflect any transactional costs or account maintenance fees. They do not include your fund’s low-balance fee, which is described in the prospectus. If this fee were applied to your account, your costs would be higher. Your fund does not charge transaction fees, such as purchase or redemption fees, nor does it carry a “sales load.”

The calculations assume no shares were bought or sold during the period. Your actual costs may have been higher or lower, depending on the amount of your investment and the timing of any purchases or redemptions.

You can find more information about the fund’s expenses, including annual expense ratios, in the Financial Statements section of this report. For additional information on operating expenses and other shareholder costs, please refer to the appropriate fund prospectus.

1 This table does not include data for funds or share classes of funds with fewer than six months of history.

2 The calculations are based on expenses incurred in the most recent six-month period. The funds’ annualized six-month expense ratios for that period are: 0.21% for the Growth Index Fund Investor Shares, 0.10% for Admiral Shares, 0.07% for Institutional Shares, and 0.10% for ETF Shares; 0.20% for the Value Index Fund Investor Shares, 0.10% for Admiral Shares, 0.07% for Institutional Shares, and 0.10% for ETF Shares; 0.19% for the Large-Cap Index Fund Investor Shares, 0.11% for Admiral Shares, 0.07% for Institutional Shares, and 0.06% for ETF Shares; 0.18% for the Total Stock Market Index Fund Investor Shares, 0.09% for Admiral Shares, 0.05% for Institutional Shares, and 0.06% for ETF Shares. The dollar amounts shown as “Expenses Paid” are equal to the annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent six-month period, then divided by the number of days in the most recent 12-month period.

Glossary

Beta. A measure of the magnitude of a fund’s past share-price fluctuations in relation to the ups and downs of a given market index. The index is assigned a beta of 1.00. Compared with a given index, a fund with a beta of 1.20 typically would have seen its share price rise or fall by 12% when the index rose or fell by 10%. A fund’s beta should be reviewed in conjunction with its R-squared (see definition below). The lower the R-squared, the less correlation there is between the fund and the index, and the less reliable beta is as an indicator of volatility.

Earnings Growth Rate. The average annual rate of growth in earnings over the past five years for the stocks now in a fund.

Expense Ratio. The percentage of a fund’s average net assets used to pay its annual administrative and advisory expenses. These expenses directly reduce returns to investors.

Foreign Holdings. The percentage of a fund represented by stocks or depositary receipts of companies based outside the United States.

Inception Date. The date on which the assets of a fund (or one of its share classes) are first invested in accordance with the fund’s investment objective. For funds with a subscription period, the inception date is the day after that period ends. Investment performance is measured from the inception date.

Median Market Cap. An indicator of the size of companies in which a fund invests; the midpoint of market capitalization (market price x shares outstanding) of a fund’s stocks, weighted by the proportion of the fund’s assets invested in each stock. Stocks representing half of the fund’s assets have market capitalizations above the median, and the rest are below it.

Price/Book Ratio. The share price of a stock divided by its net worth, or book value, per share. For a fund, the weighted average price/book ratio of the stocks it holds.

Price/Earnings Ratio. The ratio of a stock’s current price to its per-share earnings over the past year. For a fund, the weighted average P/E of the stocks it holds. P/E is an indicator of market expectations about corporate prospects; the higher the P/E, the greater the expectations for a company’s future growth.

R-Squared. A measure of how much of a fund’s past returns can be explained by the returns from the market in general, as measured by a given index. If a fund’s total returns were precisely synchronized with an index’s returns, its R-squared would be 1.00. If the fund’s returns bore no relationship to the index’s returns, its R-squared would be 0.

Return on Equity. The annual average rate of return generated by a company during the past five years for each dollar of shareholder’s equity (net income divided by shareholder’s equity). For a fund, the weighted average return on equity for the companies whose stocks it holds.

Short-Term Reserves. The percentage of a fund invested in highly liquid, short-term securities that can be readily converted to cash.

Turnover Rate. An indication of the fund’s trading activity. Funds with high turnover rates incur higher transaction costs and may be more likely to distribute capital gains (which may be taxable to investors). The turnover rate excludes in-kind transactions, which have minimal impact on costs.

Yield. A snapshot of a fund’s income from interest and dividends. The yield, expressed as a percentage of the fund’s net asset value, is based on income earned over the past 30 days and is annualized, or projected forward for the coming year. The index yield is based on the current annualized rate of income provided by securities in the index.

The People Who Govern Your Fund

The trustees of your mutual fund are there to see that the fund is operated and managed in your best interests since, as a shareholder, you are a part owner of the fund. Your fund’s trustees also serve on the board of directors of The Vanguard Group, Inc., which is owned by the Vanguard funds and provides services to them on an at-cost basis.

A majority of Vanguard’s board members are independent, meaning that they have no affiliation with Vanguard or the funds they oversee, apart from the sizable personal investments they have made as private individuals.

Our independent board members bring distinguished backgrounds in business, academia, and public service to their task of working with Vanguard officers to establish the policies and oversee the activities of the funds. Among board members’ responsibilities are selecting investment advisors for the funds; monitoring fund operations, performance, and costs; reviewing contracts; nominating and selecting new trustees/directors; and electing Vanguard officers.

Each trustee serves a fund until its termination; or until the trustee’s retirement, resignation, or death; or otherwise as specified in the fund’s organizational documents. Any trustee may be removed at a shareholders’ meeting by a vote representing two-thirds of the net asset value of all shares of the fund together with shares of other Vanguard funds organized within the same trust. The table on these two pages shows information for each trustee and executive officer of the fund. The mailing address of the trustees and officers is P.O. Box 876, Valley Forge, PA 19482.

EX-99.CODE ETH

THE VANGUARD FUNDS’
CODE OF ETHICS
FOR
SENIOR EXECUTIVE AND FINANCIAL OFFICERS

I. Introduction

        The Board of Trustees of each registered investment company that is managed, sponsored, and distributed by The Vanguard Group, Inc. (“VGI”) (each a “Vanguard Fund” and collectively the “Vanguard Funds”) has adopted this code of ethics (the “Code”) as required by Section 406 of the Sarbanes-Oxley Act. The Code applies to the individuals in positions listed on Exhibit A (the “Covered Officers”). All Covered Officers, along with employees of The Vanguard Group, Inc., are subject to separate and distinct obligations from this Code under a Code of Ethics adopted pursuant to Rule 17j-1 under the Investment Company Act of 1940 (“17j-1 Code of Ethics”), policies to prevent the misuse of non-public information, and other internal compliance guidelines and policies that may be in effect from time to time.

This Code is designed to promote:

• Honest and ethical conduct, including the ethical handling of conflicts of interest;

• Full, fair, accurate, timely, and understandable disclosure in reports and documents that a Vanguard Fund files with, or submits to, the U.S. Securities and Exchange Commission, or in other public communications made by the Vanguard Funds or VGI;

• Compliance with applicable laws, governmental rules, and regulations;

• Prompt internal reporting to those identified in the Code of violations of the Code; and

• Accountability for adherence to the Code.

II. Actual or Apparent Conflicts of Interest

    A.        Covered Officers should conduct all activities in accordance with the following principles:

1. Shareholders’ interests come first. In the course of fulfilling their duties and responsibilities to Vanguard Fund shareholders, Covered Officers must at all times place the interests of Vanguard Fund shareholders first. In particular, Covered Officers must avoid serving their own personal interests ahead of the interests of Vanguard Fund shareholders.

2. Conflicts of interest must be avoided. Covered Officers must avoid any situation involving an actual or potential conflict of interest or possible impropriety with respect to their duties and responsibilities to Vanguard Fund shareholders.

3. Compromising situations must be avoided. Covered Officers must not take advantage of their position of trust and responsibility. Covered Officers must avoid any situation that might compromise or call into question their exercise of full independent judgment in the best interests of Vanguard Fund shareholders.

All activities of Covered Officers should be guided by and adhere to these fiduciary standards regardless of whether the activity is specifically described in this Code.

B. Restricted Activities

1. Prohibition on secondary employment. Covered Officers are prohibited from accepting or serving in any form of secondary employment. Secondary employment that does not create a potential conflict of interest may be approved by the General Counsel of VGI.

2. Prohibition on service as director or public official. Unless approved by the General Counsel of VGI, Covered Officers are prohibited from serving on the board of directors of any publicly traded company or in an official capacity for any federal, state, or local government (or governmental agency or instrumentality).

3. Prohibition on misuse of Vanguard time or property. Covered Officers are prohibited from making use of time, equipment, services, personnel or property of any Vanguard entity for any purposes other than the performance of their duties and responsibilities in connection with the Vanguard Funds or other Vanguard-related entities.

III. Disclosure and Compliance

A. Each Covered Officer should be familiar with the disclosure requirements generally applicable to the Vanguard Funds.

B. Each Covered Officer should not knowingly misrepresent, or cause others to misrepresent, facts about the Vanguard Funds to others, including to the Vanguard Funds’ directors and auditors, or to government regulators and self-regulatory organizations.

C. Each Covered Officer should, to the extent appropriate within the Covered Officer’s area of responsibility, consult with other officers and employees of VGI and advisers to a Vanguard Fund with the goal of promoting full, fair, accurate, timely and understandable disclosure in the reports and documents the fund files with, or submits to, the SEC and in other public communications made by a Vanguard Fund.

D. It is the responsibility of each Covered Officer to promote compliance with the standards and restrictions imposed by applicable laws, rules, regulations, and the 17j-1 Code of Ethics.

2

IV. Reporting and Accountability

    A.        Each Covered Officer must:

1. Upon adoption or amendment of the Code (or thereafter as applicable, upon becoming a Covered Officer), affirm in writing that he or she has received, read, and understands the Code;

2. Affirm at least annually in writing that he or she has complied with the requirements of the Code;

3. Not retaliate against any other Covered Officer or any employee of VGI for reports of potential violations of the Code that are made in good faith; and

4. Notify the General Counsel of VGI promptly if the Covered Officer knows of any violations of this Code.

    B.        The Vanguard Funds will use the following procedures in investigating and enforcing this Code:

1. The General Counsel of VGI is responsible for applying this Code to specific situations and has the authority to interpret this Code in any particular situation. The General Counsel will report on an as-needed basis to the Board of Trustees regarding activities subject to the Code.

2. The General Counsel will take all appropriate action to investigate any potential violations of the Code that are reported to him.

3. If, after investigation, the General Counsel believes that no material violation of the Code has occurred, the General Counsel is not required to take any further action.

4. Any matter that the General Counsel believes is a material violation of the Code will be reported to the Board of Trustees of the Vanguard Funds.

5. If the Board of Trustees of the Vanguard Funds concurs that a material violation of the Code has occurred, the Board will consider appropriate action. Appropriate action may include reassignment, suspension, or dismissal of the applicable Covered Officer(s), or any other sanctions the Board deems appropriate. Appropriate action may also include review of, and appropriate modifications to, applicable policies and procedures.

6. Any changes to or waiver of this Code will, to the extent required, be disclosed as provided by SEC rules.

3

V. Other Policies and Procedures

        This Code shall be the sole code of conduct adopted by the Vanguard Funds for purposes of Section 406 of the Sarbanes-Oxley Act and the rules and forms applicable to registered investment companies thereunder. Insofar as other policies or procedures of the Vanguard Funds, VGI, or other service providers govern or purport to govern the behavior or activities of the Covered Officers, they are superseded by this Code to the extent that they overlap or conflict with the provisions of this Code.

        VGI’s and the Vanguard Funds’ 17j-1 Code of Ethics, policies to prevent the misuse of non-public information, and other internal compliance guidelines and policies that may be in effect from time to time are separate requirements applying to the Covered Officers and others, and are not part of this Code.

VI. Amendments

        This Code may not be materially amended except by the approval of a majority vote of the independent trustees of the Vanguard Funds’ Board of Trustees. Non-material, technical, and administrative revisions of the Code do not have to be approved by the Board of Trustees. Amendments must be in writing and communicated promptly to the Covered Officers, who shall affirm receipt of the amended Code in accordance with Section IV. A. 1.

VII. Confidentiality

        All reports and records prepared or maintained pursuant to this Code shall be considered confidential and shall be maintained and protected accordingly. Except as otherwise required by law or this Code, such matters shall not be disclosed to anyone other than the Vanguard Funds’ Board of Trustees and VGI’s General Counsel.
