violence in iraq

The only two systematic studies of trends in Iraqi mortality rates over time were conducted by researchers from Johns Hopkins University, and were published in October 2004 and October 2006 in the medical journal The Lancet. The first study estimated “about 100,000 excess [Iraqi] deaths”—meaning 98,000 more Iraqis died than would have had the invasion/occupation not occurred; the October 2006 estimated 655,000 excess Iraqi deaths.
... the studies concluded that the US-led forces were largely responsible for those deaths: the first study found that “[v]iolence accounted for most of the excess deaths and air strikes from coalition forces accounted for most violent deaths.” In other words, the 100,000 excess deaths could be “mainly attributed to coalition forces”. The October 2006 follow-up found that “[t]he proportion of deaths ascribed to coalition forces” had diminished to 31 percent by 2006, “although the actual numbers ha[d] increased every year.” And US-led forces were still found to be responsible for a higher percentage (31) of deaths than any other group or cause in Iraq.
