The map above was produced with data from the Iraq Coalition Casualty Count web site. Once you are there, click on a state to get detailed information. It has city-by-city details of forces who have died or been injured in Iraq. The information is collected from several sources, including Centcom, the Multi-National Force of Iraq, news reports and the Department of Defense. All reports must be confirmed by the Department of Defense to be counted.

Who's doing the counting? Here's an excerpt from the site:

This site is maintained by amateurs. We have no affiliation with the government, think tanks, or news organizations. The site is maintained during the early morning hours, late at night, and during lunch breaks. This site is provided as a free service and is self financed with cost off set by user donations.

Their records match the Department of Defense in most cases. Casualties that have not yet been confirmed are listed but identified as such.
