The Jews killed represented around one third of world Jewry[417] and about two-thirds of European Jewry, based on a pre-war figure of 9.7 million Jews in Europe.[418] Most heavily concentrated in the east, the pre-war Jewish population in Europe was 3.5 million in Poland; 3 million in the Soviet Union; nearly 800,000 in Romania, and 700,000 in Hungary. Germany had over 500,000.[416] The death camps in occupied Poland accounted for half the Jews murdered. At Auschwitz, the number of Jewish victims was 960,000;[419] Treblinka 870,000;[164] Bełżec 600,000;[160] Chełmno 320,000;[161] Sobibór 250,000;[163] and Majdanek 79,000.[162] The most commonly cited death toll is the six million given by Adolf Eichmann to SS member Wilhelm Höttl, who signed an affidavit mentioning this figure in 1945.[420][ac] Historians' estimates range from 4,204,000 to 7,000,000.[422] According to Yad Vashem, "[a]ll the serious research" confirms that between five and six million Jews were murdered.[ac]
