This report presents various governmental and nongovernmental estimates of Iraqi civilian dead and wounded. The Department of Defense (DOD) regularly updates total U.S. military death and wounded statistics from Operation Iraqi Freedom (OIF). However, no Iraqi or U.S. government office regularly releases publicly available statistics on Iraqi civilian deaths or civilians who have been wounded. Statistics on Iraqi civilian dead and wounded are sometimes available through alternative sources, such as nonprofit organizations, or through statements made by officials to the press. Because these estimates are based on varying time periods and have been created using differing methodologies, readers should exercise caution when using these statistics and should look on them as guideposts rather than as statements of fact.

This report discusses the "oil-for-food" program (OFFP) as the centerpiece of a long-standing U.N. Security Council effort to alleviate human suffering in Iraq while maintaining key elements of the 1991 Gulf war-related sanctions regime. The program, in operation from December 1996 until March 2003, is detailed.
