Getty, Rittersporn and Zemskov recently claimed that no more than 2 million people could have perished from collectivization, famine, execution, terror, and forced labor in the USSR during the 1930s. Prior demographic confirmation of this estimate was provided by Anderson and Silver who contended that killings were unlikely to exceed a few million and could not be more than 4.8 million victims. This essay disproves both these contentions by introducing new demographic evidence proving that Stalin killed at least 5.2 million Soviet citizens 1927-1938, with a best estimate in the vicinity of 10 million.
