You ignore the fact that the commissioners were not the only ones to work with the data.
Probably every project have specific professionals (including mathematicians, computer analysts and librarians) working under the instructions of the directors.
Every project?
Utter rubbish. You clearly have no idea how academia works if you think there are usually 'specific professionals' working on research projects in the social sciences and humanities. Most research projects consist of precisely one researcher. A PhD is a research project. One year of research leave for a single researcher is a research project.
Coordinated research projects with large grants may consist of a principal investigator, 1-3 postdocs and maybe a couple of PhD students. They will use computer software
if appropriate. Some will be interdisciplinary, but the disciplines will be the ones where there is analysis to be done, not 'mathematicians, computer analysts and librarians'.
Your three examples from the Dresden commission are all still working as historians. Neutzer like Bergander is a local historian according to the listing, not a professional, not an academic computer scientist or mathematician or statistician, qualified as an engineer with no doctorate. Overmans and Mueller were employed by the MGFA as historians. I already said Overmans did excellent statistical work on Wehrmacht casualties and was precisely the kind of guy to have on such a project.
Yet for all the effort, they still could not produce a result more precise than 'up to 25,000'.
If you think this is a required standard, you are engaged in special pleading and trying to obfuscate how history should be written by demanding standards that do not exist in the real world. Historians use the best information they can in their scholarship (and not when chatting on internet forums), and they use whatever tools they can. But those tools do not usually have to involve anything more complex than reading documents and using a calculator.
So?
That number is more precise than the numbers provided by your "courtesy".
It took a 96 page report to be so "precise", not a few paragraphs on an internet forum written from memory.
You don't really seem to understand where historical statistics usually come from - documents.
I said for example that Dutch Jews were subjected to a systematic registration in 1941 - this registered exactly 140,001 'full Jews' by Nazi definitions, defined by number of Jewish grandparents and membership of the Jewish religious community. Half- and quarter Jews were exempted from deportation as in Germany in this Germanic country. The 1941 registration is a source, a document. There is nothing much to query with the figure, it is like any census or any official report.
Other documents - transport lists, records of Westerbork, the SS and the Jewish council, overlapping with each other - indicate that exactly 103,019 Jews were deported from the Netherlands to Auschwitz, Sobibor, Theresienstadt and Belsen. Further transports lacking precise documentation took another 2000 Jews to Mauthausen, Buchenwald and other camps. The documents were identified and compiled already in the 1940s, and the number has not changed since then.
The data is repeated in multiple sources; mine is Gerhard Hirschfeld, 'Niederlande' in Wolfgang Benz (ed), Dimension des Völkermords. Die Zahl der jüdischen Opfer des Nationalsozialismus. Munich, 1991, pp.138-165, the numbers appearing in multiple locations in this chapter. Other sources give the same figures (Presser, de Jong, Moore, Croes).
Thus, when I stated from memory that 80% of Jews in the Netherlands were deported I was too high by about 5-6%, since the real percentage is 73.5% for the precisely documented transports and 74.9% including the less precisely documented transports.
My original point still stands: Jews in the Netherlands were registered systematically because of the fact that the Dutch population registration bureaucracy was efficient, and because there was a census identifying religion, the 1930 census counting 111,917 (Hirschfeld, p.138, citing E. Boekman, Demografie van de Joden in Nederland, Amsterdam, 1936, p.3), a number which significantly increased because of the influx of refugees from Germany in the 1930s (like the Frank family).
When deportations started, Jews in mixed marriages were exempted; they numbered 10,500; there were other initially exempted categories who were later added to the transports (and often sent to Theresienstadt as a concession to their previously privileged status). But many went underground. Some were caught before the autumn of 1944 and deported, like the Frank family. Some were not.
The number who went underground cannot be known with absolute precision. But it is no different to asking how many people in Dresden sheltered in cellars or sheltered in public air raid shelters. Interesting to know, but a subject for lots of research by specialists; much like it took 66 years for the Dresden Commission to do its job. The current estimates suggest 20,000 went underground over the war, or better than 1 in 7 of the target group.
Three Dutch demographers and historians, van Imhoff, van Solinge and Film, wrote a study which exploited among other sources the NIOD database of survivors which records 13,557 Jews survived in hiding. NIOD is the Netherlands Institute for War Documentation, an official government research institute. The database is of course computerised. This suggests that 6-7,000 Jews were caught while in hiding, a number which has some documentation from German police reports of the Befehlshaber der Sicherheitspolizei Niederlande as well as the Westerbork documents; and which obviously includes the Frank family. Bluespaceoddity and ddt can tell you more about this, as they already have, including how rewards as well as manhunts and threats worked to help catch Jews in hiding.
Imhoff et al published their work on Dutch Jewish demography in Population Research and Policy Review, Vol. 20, 2001, pp.457-481. The work compares very well with other demographic studies, eg France Mesle and Jacques Vallin, Jacques,
Mortalite et causes de deces en Ukraine au XXe siecle. Paris, 2003; detailing the complex demography of the Ukraine in the 20th Century, with especial emphasis on the 1930s and the 1932-33 famine as well as the Great Terror. The same scholars also published a study specifically on the 1930s and 1940s (Vallin, Jacques, Mesle, France, Adamets, Serguei, Pyrozhkov, Serhii, ‘A New Estimate of Ukrainian Population Losses during the Crises of the 1930s and 1940s’, Population Studies 56/3, 2002, pp.249-264).
By contrast, while the number of Jews deported from France is precisely known and documented (see Klarsfeld, Serge, Memorial to the Jews Deported from France 1942- 1944. New York: Beate Klarsfeld Foundation, 1983; the same data can be found all over the internet with a google search for e.g juifs convoi France 1942 1944 or Jews deported France), the number of Jews living in France in 1940 or 1942 will never be known precisely, since there was no census and no systematic registration.
The estimates at the time were that 300-350,000 Jews lived in metropolitan France. The Nazis estimated more by including the colonies in French North Africa. My figure was that 25% of French Jews were deported. This took the lower end of the estimate range to produce a simple statistic, since it is well known and easily checked that 75,000 French Jews were deported, rounding off. Since the precise number of Jews in France will never be known, any further objections are irrelevant.
So in both these cases, your trolling is simply that; ignorant of the literature on the Holocaust in the Netherlands and France, ignorant of the sources, and hilariously ignorant of historical methodology, since there is no need to use computer databases to produce simple percentages out of well known figures. One only need use books and documents.
I have written the above not for you, but for other readers, since you have repeatedly proven you are wilfully ignorant of logic, methodology and simple debate courtesies. You may reply if you wish, but I am placing you on ignore since you have forfeited any remaining courtesy from me, and from several others, it seems. If I were you, I'd reflect on that.
