As well as this monstrous programme of extermination, the human cost of the war was appalling for most of the belligerents. The USSR lost the most—at least 20 million civilian and military personnel killed—including large numbers of Russian prisoners deliberately starved to death in German prisoner-of-war camps. Poland lost around a fifth of its civilian population. Allied civilian losses were 44 million; Axis losses, 11 million. The military deaths on both sides in Europe numbered 19 million, and in the war against Japan, 6 million (which included a sizeable number of Allied prisoners-of-war starved or tortured to death in Japanese forced-labour camps in Burma and elsewhere). Only the United States was spared any significant civilian losses, with 292,131 military deaths in battle and 115,187 military deaths from other causes.
The highest numbers of deaths, military and civilian, were as follows: USSR more than 10 million military and 10 million civilian; China 3.5 million and 10 million; Germany 3.5 million and 3.8 million; Poland 120,000 and 5.3 million; Japan 1.7 million and 380,000; Yugoslavia 300,000 and 1.3 million; Romania 200,000 and 465,000; France 250,000 and 360,000; British Empire 452,000 and 60,000; Italy 330,000 and 80,000; Hungary 120,000 and 280,000; and Czechoslovakia 10,000 and 330,000.

USSR casualties are represented roughly. Stalin wanted to cut down on human losses. I studied that about 30 million people were lost in total!
