The initial report, sixteen pages long, was submitted on March 23, 1943. On Himmler's request an abridged version, six-and-a-half pages long, was updated to March 31, 1943. After the initial report was made and delivered to Himmler, he requested that he receive short monthly reports there after. The full report summarized how many
Jews remained in Germany, Austria and Europe; detailed the numbers of Jews detained in the
Nazi concentration camps; how many Jews had died natural deaths since 1933; and how many Jews had been evacuated to the eastern territories. The report calculated that, from 1937 to December 1942, the number of Jews in Europe had fallen by 4 million. Korherr ascribed this fall to "emigration, partially due to the excess mortality of the Jews in Central and Western Europe, partially due to the evacuations especially in the more heavily populated Eastern Territories, which are here counted as ongoing." By way of explanation, Korherr added that It must not be overlooked in this respect that of the deaths of Soviet Russian Jews in the occupied Eastern territories only a part was recorded, whereas deaths in the rest of European Russia and at the front are not included at all. In addition there are movements of Jews inside Russia to the Asian part which are unknown to us. The movement of Jews from the European countries outside the German influence is also of a largely unknown order of magnitude. On the whole European Jewry should since 1933, i.e. in the first decade of National Socialist German power, have lost almost half of its population. ==Post-war==
