American War and Military Operations Casualties: Lists and Statistics [September 14, 2018] [open pdf - 2MB]
"This report provides war casualty statistics. It includes data tables containing the number of fatalities and the number of wounded among American military personnel who served in principal wars and combat actions from 1775 to the present. It also includes information such as race and ethnicity, gender, branch of service, and, in some cases, detailed information on types of casualties and causes of death.Casualty statistics for wars that ended long ago are updated periodically, sometimes yearly. These updates almost always reflect the identification of remains of persons previously listed as missing in action and the reclassification of those persons as dead. Other reasons, much less frequent, include the discovery of errors in casualty records for individuals or categories such as race and ethnicity."
