One Holocaust denial argument is the comparison of the population of Jews before and after the Holocaust. They state that the 1940 World Almanac gives the world Jewish population as 15,319,359, while the 1948 World Almanac gives the world Jewish population as 15,713,638. They therefore claim that either the figures are wrong, or the Holocaust, meaning the deaths of millions of Jews, cannot have happened to any extent similar to the claimed 6 million. Ken McVay writes:
Only in 1949 are postwar estimates employed, the figures given are for estimates made in 1948. A year or two lag seems to be common for various other population estimates given by the World Almanac. The difference between the 1938 and 1948 figures is thus 4,481,491. In 1949, however, the World Almanac gives a revised 1939 population of 16,643,120 giving a difference of between 1938 and 1947 of 5,376,520. Where the extra population between 1938 and 1939 came from is not cited, though one might speculate that it was based upon the Nazi estimates made in 1942 for the Wannsee Conference. Despite the apparent exactness of the numbers listed, the World Almanac warns that all numbers listed are estimates.[53]
Other sources confirm similar numbers—and earlier than the 1949 World Almanac—for the Jewish population before and after the war. The 1932 American Jewish Yearbook estimate the total number of Jews in the world at 15,192,218, of whom 9,418,248 resided in Europe. However, the 1947 yearbook states: "Estimates of the world Jewish population have been assembled by the American Jewish Joint Distribution Committee (except for the United States and Canada) and are probably the most authentic available at the present time. The figures reveal that the total Jewish population of the world has decreased by one-third from about 16,600,000 in 1939 to about 11,000,000 in 1946 as the result of the annihilation by the Nazis of more than five and a half million European Jews. In Europe only an estimated 3,642,000 remain of the total Jewish pre-war population of approximately 9,740,000." These numbers are also consistent with the findings of the Anglo-American Committee of Inquiry, Appendix III, in 1946.
