The gulag system according to Russian statistics caused 1,053,829 deaths [1] or maybe 1.6 million. The Nazi death camps alone killed 3.2 million people[2] (in a period of 4-5 years 1941-1945), not to mention the endless number of labour and POW camps where millions perished as well.
The lead editors on the project, Geoffrey Megargee and Martin Dean, estimate that 15 million to 20 million people died or were imprisoned in the sites that they have identified as part of a multivolume encyclopedia. (The Holocaust museum has published the first two, with five more planned by 2025.) The existence of many individual camps and ghettos was previously known only on a fragmented, region-by-region basis.
