World War II has been the bloodiest war in human history, killing over 60 million people. This means that around 3 percent of the entire 1939 world population died in the war. Although most battles were fought in Europe, America was very active in the war, also suffering great losses.
Nobody has exact figures, but it is estimated that around the U.S. counted around 407,000 military deaths and around 12,000 civilian deaths (due to crimes of war and military activity such as bombings.) The total death count for all Americans amounted up to 420,000.
