War's Iraqi Death Toll Tops 50,000

Many more Iraqis are believed to have been killed but not counted because of serious lapses in recording deaths in the chaotic first year after the invasion, when there was no functioning Iraqi government, and continued spotty reporting nationwide since.

The toll, which is mostly of civilians but probably also includes some security forces and insurgents, is daunting: Proportionately, it is equivalent to 570,000 Americans being killed nationwide in the last three years.

In the same period, at least 2,520 U.S. troops have been killed in Iraq.

Iraqi officials involved in compiling the statistics say violent deaths in some regions have been grossly undercounted, notably in the troubled province of Al Anbar in the west. Health workers there are unable to compile the data because of violence, security crackdowns, electrical shortages and failing telephone networks.

The Health Ministry acknowledged the undercount. In addition, the ministry said its figures exclude the three northern provinces of the semi-autonomous region of Kurdistan because Kurdish officials do not provide death toll figures to the government in Baghdad.

In the three years since Saddam Hussein's regime was toppled, the Bush administration has rarely offered civilian death tolls. Last year, President Bush said he believed that "30,000, more or less, have died as a result of the initial incursion and the ongoing violence against Iraqis."

Nongovernmental organizations have made estimates by tallying media accounts; The Times attempted to reach a comprehensive figure by obtaining statistics from the Baghdad morgue and the Health Ministry and checking those numbers against a sampling of local health departments for possible undercounts.

The Health Ministry gathers numbers from hospitals in the capital and the outlying provinces. If a victim of violence dies at a hospital or arrives dead, medical officials issue a death certificate. Relatives claim the body directly from the hospital and arrange for a speedy burial in keeping with Muslim beliefs.

If the morgue receives a body -- usually those deemed suspicious deaths -- officials there issue the death certificate.
