WASHINGTON - One person can tell you precisely how many Americans have been killed in Iraq. Another pays close attention to the names and hometowns of those who die each week. A third mourns for the families of fallen U.S. troops, but also figures it was their choice to enlist.

Americans are keenly aware of how many U.S. forces have lost their lives in Iraq, according to a new AP-Ipsos poll. But they woefully underestimate the number of Iraqi civilians who have been killed.
