World War II casualties

The Second World War (1939–1945) caused more than 40 to 85 million deaths (both military and civilian), becoming the deadliest war in human history. Most casualties came from the Soviet Union (27 million) and China (20 million) which suffered from various atrocities (genocide, massacres, forced labor, mistreatment,...) by the Axis powers (primarily Nazi Germany and the Empire of Japan) or from diseases (like malaria), starvation, bombardment, sickness and more.

Total civilian deaths were around 50 million, total military deaths were around 25 million, which made up about 3% of world's population at the time (>2 billion). The most targeted ethnic minorities were the Jewish, in which 6 million were killed by the Nazis, decreasing its population in just 5 years of war (initially it was over 9 million before war but less than 4 million after war; see the Holocaust for more information). Other targerted groups by Nazi Germany were the disabled, Slavs, Soviet POWs, Romanians, homosexual groups,.., which gave a total of 11 million people murdered (see Holocaust victims). Japan committed by far worse atrocities than the Nazis against China including the Nanjing Massacre and Unit 731 during the Second Sino–Japanese War, the long 8-years war with Japan had killed over 20 million Chinese people.

While the Allies took the heaviest losses, the Axis took some too. Germany had around 5 to 8 million deaths during the war, Japan had around 2–3 million (246,000 deaths in the atoround 400 to 500 thousand.

Total deaths from both sides are listed, some are merged with others. These include military and civilian deaths.
