World War II was the deadliest military conflict in history in absolute terms of total dead. Over 60 million people were killed, which was about 3% of the 1940 world population (est. 2.3 billion). The tables below give a detailed country-by-country count of human losses. World War II fatality statistics vary, with estimates of total dead ranging from 50 million to more than 80 million. The higher figure of over 80 million includes deaths from war-related disease and famine. Civilians killed totalled 50 to 55 million, including 19 to 28 million from war-related disease and famine. Total military dead: from 21 to 25 million, including deaths in captivity of about 5 million prisoners of war.
Recent historical scholarship has shed new light on the topic of Second World War casualties. Research in Russia since the collapse of the Soviet Union has caused a revision of estimates of Soviet war dead. According to Russian government figures USSR losses within postwar borders now stand at 26.6 million. In August 2009 the Polish Institute of National Remembrance (IPN) researchers estimated Poland's dead at between 5.6 and 5.8 million. Historian Rüdiger Overmans of the German Armed Forces Military History Research Office published a study in 2000 that estimated German military dead and missing at 5.3 million.
