My 11-y. daughter is making a year-schoolwork about children in WWII. And she wanted to know how many people were destroyed by the nazi camp system. At first I thought she is searching incorrectly and finds meaningless numbers only, but she proposed to find the number myself... And I was astonished, that I really cannot find the number.
There is a number of Jews shot or killed by gas (2.7 mln), a number of Polish victims in camps in Poland (1.2mln), Soviet soldiers killed in these Poland camps (800t), but obviously, if we want to find the whole numbers, these part ones are useless, for they overlap.
The only general number I found was 3.1-3.2 mln victims of extermination camps, but this is only about camps that were named extermination camps. Other camps or death trains or marches killed people in great numbers, too, and only smaller part of total 45000 camps were extermination ones. And 3.1mln is far less than the number of victims in 8 greatest camps in Poland only.
Also, I see no numbers for death trains and marches. And after we visited the museums of Teresin, we know, that they swallowed a significant fraction of the total number of victims. And I think, that these transports that killed people between camps, should be counted in the whole number.
Of course, the transports to camps were deadly, too (my granduncle was in one of such, and told about no-food regime for weeks), but I am afraid it is not possible to count their victims.
Do you know about some general number, either exact or at least some sensible estimation? If trains and marches cannot be covered, then at least all camps' victims number.
