The demographic evidence of the genocide is unquestioned. According to the census data furnished by the International Commission of Inquiry initiated by the World Congress of Free Ukrainians (WCFU) into the Famine of 1932-1933 in Ukraine, the number of Ukrainians in the USSR declined from 31,195,000 in 1926 to 28,111,000 in 1939[5] (in the same period, the number of Russians in the USSR increased from 77,791,000 to 99,591,000, while the number of Belarusians increased from 4,739,000 to 5,275,000).[6] In other words, during the time that the number of Russians increased by 28%, and the number of Belarusians by 11.2%, the number of Ukrainians decreased by 9.9%. Overall, the population of the USSR increased by 16%. Given this average increase, in 1939 the number of Ukrainians in the USSR should have been around 36,186,000. Thus, the decrease in the number of Ukrainians between 1926 and 1939 was about eight million people.
