They also claim that many Jews who emigrated are included in the number (What Do Holocaust). Deniers believe that it is impossible for nearly one-third of the Jews in Europe to be killed. This is why deniers assume that Jews that emigrated to Russia, Britain, Palestine, and the United States are included in the six million of supposedly dead Jews. However, since the 1940’s, scholars, Jewish organizations, and governmental agencies have used census records and other documents to estimate the number of human losses (Documenting Numbers). By comparing the number of Jews before and after the Holocaust, scholars are able to see how many Jewish disappearances occurred. Because of the mass killing that occurred between 1933 and 1940, scholars assume most disappearances were caused by the Nazi Party. In 1933, the Jewish population in Europe was 9.5 million and sixty percent of all Jews lived there. In 1950, the Jewish population in Europe was 3.5 million. This meant that only one-third of the Jewish population lived in Europe by 1950 (Jewish Population). The decrease in Jewish population in Europe happened at the same time as the Holocaust was happening. Therefore, the decline in Jewish population happening over the same time frame as the Holocaust proves that six million Jews were killed during the
