From 2003 to 2011, during the U.S.-led invasion and occupation of Iraq, for every three people killed by violence, two died as a result of the collapse of the infrustructure that supports health care, clean water, nutrition and transportation.

The study is the first population-based survey since 2006 to estimate war-related deaths in Iraq and the first to cover the full-time span of the conflict. Researchers state with 95% certainty that there were approximately 461,000 excess deaths during the Iraq war, but the actual number could be as low as 48,000 or as high as 751,000. (For comparison, three years after the 2010 earthquake in Haiti, the death toll has been estimated anywhere between 46,000 and 316,000).
In the PLOS Medicine study —"Mortality in Iraq Associated with the 2003-2011 War and Occupation: Findings from a National Cluster Sample Survey by the University Collaborative Iraq Mortality Study"—researchers detail improvements in estimating mortality during the Iraq war and emphasize the public health consequences of armed conflict. More than 60% of those deaths were directly attributable to violence while the rest were associated with indirect, but war-related, causes.
