From the history of the 1937 census of population

This is a history of the 1937 census of the USSR, the results of which were suppressed because of an alleged massive undercount. The author attempts to determine whether there was in fact an undercount in this census, and if so how significant it was. He concludes that those responsible were not guilty of producing a significant undercount, and in fact employed the methods required to keep the undercount to a bare mimimum.
