World War II casualties
Compiling or estimating the numbers of deaths and wounded caused during wars and other violent conflicts is a controversial subject. Historians often put forward many different estimates of the numbers killed and wounded during World War II. The authors of the "Oxford Companion to World War II" maintain that "casualty statistics are notoriously unreliable." The table below gives data on the number of dead and military wounded for each country, along with population information to show the relative impact of losses. When scholarly sources differ on the number of deaths in a country, a range of war losses is given, in order to inform readers that the death toll is disputed. Since casualty statistics are sometimes disputed the footnotes to this article present the different estimates by official governmental sources as well as historians. Military figures include battle deaths (KIA) and personnel missing in action (MIA), as well as fatalities due to accidents, disease and deaths of prisoners of war in captivity. Civilian casualties include deaths caused by strategic bombing, Holocaust victims, German war crimes, Japanese war crimes, population transfers in the Soviet Union, Allied war crimes, and deaths due to war related famine and disease.
