Hmmm.

According to multiple studies, it is estimated that the total number of civilians that have died in Iraq ranges from around 1.1 million to 654,000. The former being a 2008 estimate, the latter a 2006 estimate.

For the sake of this exercise, let's hypothesize that since the US invasion of Iraq in March 2003 to the present, one million (1,000,000) Iraqi civilians have been killed. Since the US didn't invade until March 20, let's assume the war began in April. So from April 2003 to January 2009 is 58 months, or 1764 days (approximately).

Given these assumptions, on average, 567 Iraqi civilians have died each day since the US invasion. Civilians, not soldiers.
