I don't have a dog in this fight. I like accuracy and the most compelling thing I saw in SunniMan's video was the World Almanac data showing no significant change in world Jewish population between 1938 and 1948. Hmmm says I. So some searching yielded the following. I don't know which is correct but here is what I found as an explanation/correction for World Almanac data:
he University of Alberta library has the World Almanac issues for the pertinent period for 1941, 1944, 1947, 1948, and 1949. The figures listed for total world Jewish population are as follows:
.....
1941 15,748,091
1944 15,192,089
1947 15,688,259
1948 15,688,259
1949 11,266,600
Now you may be wondering what happened to all those Jews in 1948-49. No fresh estimates were made between 1938 and 1947. The figures listed for 1941, 1947, and 1948 are identified as estimates made in 1938. The source for the estimate for 1944 is not given, and the numbers are listed differently than in other years. In 1944, the numbers are given as a part of a list of various world religions rather than standing on their own with a country-by-country breakdown as in the other years.
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. ......
