Summary of Significant Accounting Policies [Abstract]
Earnings Per Share, Policy [Policy Text Block]	Basic earnings per common share (EPS) excludes dilution and is computed by dividing Net income attributable to common stockholders by the weighted average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if securities or other obligations to issue common stock were exercised or converted into common stock or resulted in the issuance of common shares that then shared in our earnings. The computation of diluted EPS excludes outstanding stock options and convertible debt in certain periods in which the inclusion of such options and debt would be anti-dilutive in the periods presented.
Segment Reporting, Policy [Policy Text Block]	Our operations are both product based and geographically based, and the reportable operating segments presented below include our funeral and cemetery operations.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	We utilize the Black-Scholes option valuation model for estimating the fair value of our stock options.
Revenue Recognition, Policy [Policy Text Block]	Earnings from all our funeral merchandise and service trust investments are recognized in funeral revenues when a service is performed or merchandise is delivered. Fees charged by our wholly-owned registered investment advisor are also included in current revenues in the period in which they are earned. In addition, we are entitled to retain, in certain jurisdictions, a portion of collected customer payments when a customer cancels a preneed contract; these amounts are also recognized in current revenues Earnings from all our cemetery merchandise and service trust investments are recognized in current cemetery revenues when a service is performed or merchandise is delivered. Fees charged by our wholly-owned registered investment advisor are also included in current revenues in the period in which they are earned. In addition, we are entitled to retain, in certain jurisdictions, a portion of collected customer payments when a customer cancels a preneed contract; these amounts are also recognized in current revenues. Distributable earnings from these cemetery perpetual care trust investments are recognized in current cemetery revenues to the extent we incur qualifying cemetery maintenance costs. Fees charged by our wholly-owned registered investment advisor are also included in current revenues in the period in which they are earned.
Fair Value of Financial Instruments, Policy [Policy Text Block]	Where quoted prices are available in an active market, securities held by the common trust funds and mutual funds are classified as Level 1 investments pursuant to the three-level valuation hierarchy as required by the FVM&D Topic of the ASC. Where quoted market prices are not available for the specific security, fair values are estimated by using either quoted prices of securities with similar characteristics or an income approach fair value model with observable inputs that include a combination of interest rates, yield curves, credit risks, prepayment speeds, rating, and tax-exempt status. These funds are classified as Level 2 investments pursuant to the three-level valuation hierarchy as required by the FVM&D Topic of the ASC. The valuation of private equity and other alternative investments requires management judgment due to the absence of quoted market prices, inherent lack of liquidity, and the long-term nature of such assets. The fair value of these investments is estimated based on the market value of the underlying real estate and private equity investments. The underlying real estate value is determined using the most recent available appraisals. As of September 30, 2012, private equity instruments are valued based on reported net asset values discounted by 0% to 60% for risk and 0% to 25% for liquidity. A significant increase (decrease) in the discounts results in a directionally opposite change in the fair value of the instruments. Valuation policies and procedures are determined by our Treasury department, which reports to our Chief Financial Officer. Additionally, valuations are reviewed by our investment committee quarterly. These funds are classified as Level 3 investments pursuant to the three-level valuation hierarchy as required by the FVM&D Topic of the ASC.

These funds are classified as Level 3 investments pursuant to the three-level valuation hierarchy as required by the FVM&D Topic of the ASC. The fair values of our long-term, fixed rate loans were estimated using market prices for those loans, and therefore they are classified within Level 1 of the Fair Value Measurements hierarchy as required by the FVM&D Topic of the ASC. The bank credit agreement and the mortgage and other debt are classified within Level 3 of the Fair Value Measurements hierarchy. The fair values of these instruments have been estimated using discounted cash flow analysis based on our incremental borrowing rate for similar borrowing arrangements.
Consolidation, Variable Interest Entity, Policy [Policy Text Block]	Our funeral merchandise and service trusts are variable interest entities as defined in the Consolidation Topic of the ASC. In accordance with this guidance, we have determined that we are the primary beneficiary of these trusts, as we absorb a majority of the losses and returns associated with these trusts. Our cemetery trust investments detailed in Notes 5 and 6 are also accounted for as variable interest entities.

The merchandise and service trust investments detailed in Notes 4 and 5 are also accounted for as variable interest entities.
Consolidation, Policy [Policy Text Block]	Summary of Significant Accounting Policies Principles of Consolidation and Basis of Presentation Our unaudited condensed consolidated financial statements include the accounts of Service Corporation International (SCI) and all subsidiaries in which we hold a controlling financial interest. Our financial statements also include the accounts of the funeral merchandise and service trusts, cemetery merchandise and service trusts and cemetery perpetual care trusts in which we have a variable interest and are the primary beneficiary. Our interim condensed consolidated financial statements are unaudited but include all adjustments, consisting of normal recurring accruals and any other adjustments, which management considers necessary for a fair statement of our results for these periods. Our unaudited condensed consolidated financial statements have been prepared in a manner consistent with the accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2011, unless otherwise disclosed herein, and should be read in conjunction therewith. The accompanying year-end condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America. Operating results for interim periods are not necessarily indicative of the results that may be expected for the full year period.

Operating results for interim periods are not necessarily indicative of the results that may be expected for the full year period. Use of Estimates in the Preparation of Financial Statements The preparation of the unaudited condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions as described in our Annual Report on Form 10-K for the year ended December 31, 2011. These estimates and assumptions may affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. As a result, actual results could differ from these estimates. Preneed Funeral and Cemetery Receivables We sell preneed funeral and cemetery contracts whereby the customer enters into arrangements for future merchandise and services prior to the time of need. As these contracts are prior to the delivery of the related goods and services, the preneed funeral and cemetery receivables are offset by a comparable deferred revenue amount. These receivables generally have an interest component for which interest income is recorded when the interest amount is considered collectible and realizable, which typically coincides with cash payment. We do not accrue interest on financing receivables that are not paid in accordance with the contractual payment date given the nature of our goods and services, the nature of our contracts with customers, and the timing of the delivery of our services. We do not consider receivables to be past due until the service or goods are required to be delivered at which time the preneed receivable is paid or reclassified as a trade receivable with payment terms of less than 30 days. As the preneed funeral and cemetery receivables are offset by comparable deferred revenue amounts, we have no risk of loss related to these receivables. If a preneed contract is canceled prior to delivery, state or provincial law determines the amount of the refund owed to the customer, if any, including the amount of the attributed investment earnings. Upon cancellation, we receive the amount of principal deposited to the trust and previously undistributed net investment earnings and, where required, issue a refund to the customer. We retain excess funds, if any, and recognize the attributed investment earnings (net of any investment earnings payable to the customer) as revenue in the consolidated statement of operations. In certain jurisdictions, we may be obligated to fund any shortfall if the amount deposited by the customers exceed the funds in trust. Based on our historical experience, we have provided an allowance for cancellation of these receivables, which is recorded as a reduction in receivables with a corresponding offset to deferred revenue. Fair Value Measurements In May 2011, the Financial Accounting Standards Board (FASB) amended the Fair Value Measurements and Disclosure (FVM&D) Topic of the Accounting Standards Codification (ASC) to expand disclosures about items marked to fair value that are categorized within Level 3 of the fair value hierarchy to include qualitative explanations of the valuation methodology used, sensitivity analysis of the inputs into the valuation, and quantitative information about those inputs. The amendment also requires that items that are not measured at fair value but for which the fair value is disclosed also disclose the level in the fair value hierarchy in which those items were categorized. We adopted the amended guidance in the first quarter of 2012 and the appropriate disclosures are contained in Notes 4, 5, and 6. Comprehensive Income In June 2011, the FASB amended the Comprehensive Income Topic of the ASC to require the disclosure of the components of other comprehensive income, which we previously disclosed elsewhere in our filings, be shown as either part of one statement of comprehensive income or as a separate statement of comprehensive income immediately following the income statement. We adopted the amended guidance in the first quarter of 2012 and a separate Statement of Comprehensive Income is included herein.
