War and occupation directly and indirectly claimed the lives of about a half-million Iraqis from 2003 to 2011, according to a survey of 1,960 Iraqi households presented by Amy Hagopian of the University of Washington in 2013.
The survey responses point to around 405,000 deaths attributable to the war and occupation in Iraq from 2003 to 2011. At least another 56,000 deaths should be added to that total from households forced to flee Iraq, the study authors estimate.
According to Iraq Body Count, total violent deaths including combatants reached nearly 200,000 until the middle of October 2014, of which 130,924–147,009 were documented civilian deaths from violence.
Some 4,805 U.S., British, and other coalition armed service members died in the invasion and occupation of Iraq in 2003-2014.
