Also, it is worth noting that many estimates of the numbers of hunger victims, especially unprofessional or biased ones, are based on a superficial comparison of the census data of the 1926th and 1937-39th years, without taking into account migration, mixing and assimilation, which played a very significant role. Comparison of the relevant data shows, in particular, a decrease in the number of Ukrainians and Kazakhs during the intercensal period and throughout whole USSR, and a very large, almost abnormal, increase of the number of Russians.
