Objective [Heading]	rr_ObjectiveHeading	Investment Objective
Objective, Primary [Text Block]	rr_ObjectivePrimaryTextBlock	The iShares MSCI Emerging Markets Minimum Volatility Index Fund (the "Fund") seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the MSCI Emerging Markets Minimum Volatility Index (the "Underlying Index").
Expense [Heading]	rr_ExpenseHeading	Fees and Expenses
Expense Narrative [Text Block]	rr_ExpenseNarrativeTextBlock	The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares, Inc. (the "Company") and BlackRock Fund Advisors ("BFA") (the "Investment Advisory Agreement") provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses. BFA, the investment adviser to the Fund, has contractually agreed to waive a portion of its management fees in order to limit Total Annual Operating Expenses to 0.25% of average daily net assets until December 31, 2014. You may also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Portfolio Turnover [Heading]	rr_PortfolioTurnoverHeading	Portfolio Turnover.
Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund's performance.

Expense Example [Heading]	rr_ExpenseExampleHeading	Example.
Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:
Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Underlying Index has been developed by MSCI Inc. ("MSCI") to measure the performance of equity securities in global emerging markets that have lower absolute volatility. The Underlying Index begins with the MSCI Emerging Markets Index, which is a capitalization-weighted index, and then follows a rules-based methodology to determine optimal weights for securities in the index with the lowest total risk. As of September 1, 2011, the Underlying Index consisted of companies in the following 19 countries: Brazil, Chile, China, Colombia, the Czech Republic, Egypt, India, Indonesia, Malaysia, Mexico, Morocco, Peru, the Philippines, Poland, Russia, South Africa, South Korea, Taiwan and Thailand. Component companies include consumer staples, financials and telecommunication services companies. BFA uses a "passive" or indexing approach to try to achieve the Fund's investment objective. Unlike many investment companies, the Fund does not try to "beat" the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued. Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies. BFA uses a representative sampling indexing strategy to manage the Fund. "Representative sampling" is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index. The Fund generally invests at least 90% of its assets in securities of the Underlying Index or in depositary receipts representing securities in the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index, futures contracts, options on futures contracts, options and swaps related to its Underlying Index, as well as cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates. The Fund will invest all of its assets that are invested in India in a wholly-owned subsidiary located in the Republic of Mauritius (the "Subsidiary"). BFA will serve as investment adviser to both the Fund and the Subsidiary. Unless otherwise indicated, the term "Fund," as used in this prospectus (the "Prospectus"), means the Fund and/or the Subsidiary, as applicable. The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of the collateral received). The Underlying Index is sponsored by an organization (the "Index Provider") that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund's Index Provider is MSCI. Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Risk [Heading]	rr_RiskHeading	Summary of Principal Risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value per share ("NAV"), trading price, yield, total return and ability to meet its investment objective. Asset Class Risk. Securities in the Underlying Index or in the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes. *Commodity Exposure Risk.* The Fund invests in economies that are susceptible to fluctuations in certain commodity markets. Any negative changes in commodity markets could have an adverse impact on those economies. *Concentration Risk.* To the extent that the Fund's investments are concentrated in a particular issuer, region, country, market, industry or asset class, the Fund may be susceptible to loss due to adverse occurrences affecting that issuer, region, country, market, industry or asset class. *Consumer Staples Sector Risk.* The consumer staples sector may be affected by marketing campaigns, changes in consumer demands, government regulations and changes in commodity prices. Currency Risk. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar. Custody Risk. Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories. Emerging Markets Risk. The Fund's investments in emerging markets may be subject to a greater risk of loss than its investments in more developed markets. Emerging markets may be more likely to experience inflation, political turmoil and rapid changes in economic conditions than more developed markets. Emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risk associated with custody of securities. Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes. Financials Sector Risk. Performance of companies in the financials sector may be adversely impacted by many factors, including government regulations, economic conditions, changes in interest rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted. Geographic Risk. A natural or other disaster could occur in a geographic region in which the Fund invests, which could affect the economy or operations of the specific geographic region, causing an adverse impact on the Fund's investments in the affected region. Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline. Management Risk. As the Fund does not fully replicate the Underlying Index, it is subject to the risk that BFA's investment management strategy may not produce the intended results. Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND'S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. Mid-Capitalization Companies Risk. The Fund may invest in the securities of mid-capitalization companies. Compared to large-capitalization companies, mid-capitalization companies may be less stable and more susceptible to adverse developments and their securities may be more volatile and less liquid. Non-Diversification Risk. The Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund's performance may depend on the performance of a small number of issuers. Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market. The Fund is also particularly exposed to Asian Economic Risk, and Central and South American Economic Risk. Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets. Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. Privatized entities may lose money or be re-nationalized. Reliance on Trading Partners Risk. The Fund invests in economies of countries that are heavily dependent upon trading with key partners. Any reduction in this trading may cause an adverse impact on the Fund's investments. Risk of Investing in India. Investment in Indian issuers involves risks that are specific to India, including legal, regulatory, political and economic risks. The securities markets in India are relatively underdeveloped and may subject the Fund to higher transaction costs or greater uncertainty than investments in more developed securities markets. Such risks may adversely affect the value of the Fund's investments. *Russian Securities Risk.* Investing in Russian securities involves significant risks, including risks associated with the settlement of portfolio transactions and the risk of loss of the Fund's ownership rights in its portfolio securities, as a result of the system of share registration and custody in Russia. *Securities Lending Risk.* The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund's loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund. *Securities Market Risk.* Non-U.S. securities markets may trade a small number of securities and may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of holdings difficult or impossible at times. Security Risk. Some countries and regions in which the Fund invests have experienced security concerns. Incidents involving a country's or region's security may cause uncertainty in these markets and may adversely affect their economies and the Fund's investments. Structural Risk. The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability. *Telecommunications Sector Risk.* Companies in the telecommunications sector may be affected by industry competition, substantial capital requirements, government regulation and obsolescence of telecommunications products and services due to technological advancement. Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index. Treaty/Tax Risk. The Fund and the Subsidiary rely on the Double Tax Avoidance Agreement between India and Mauritius ("DTAA") for relief from certain Indian taxes. Treaty renegotiation or legislative changes may result in higher taxes and lower returns for the Fund. Valuation Risk. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's shares. Volatility Risk. Although the Underlying Index was created by the Index Provider to seek lower volatility than the MSCI Emerging Markets Index, there is no guarantee that these strategies will be successful. The Fund's name reflects the name of the Underlying Index as provided by the Index Provider. However, the Index Provider may be unsuccessful in creating an index that minimizes volatility, and there is a risk that the Fund may experience more than minimum volatility. Securities in the Fund's portfolio may be subject to price volatility and the prices may not be any less volatile than the market as a whole and could be more volatile.
