e significant numbers of Poles, Germans, Jews, and others in the Ukrainian workforce), industrial laborers had already adopted Russian culture and language to a significant extent. Workers whose ethnicity was Ukrainian were not attracted to campaigns of Ukrainianization or de-Russification in meaningful numbers, but remained loyal members of the Soviet working class. There was no significant antagonism between workers identifying themselves as Ukrainian or Russian.

The industrialisation had a heavy cost for the peasantry, demographically a backbone of the Ukrainian nation. To satisfy the state's need for increased food supplies and to finance industrialisation, Stalin instituted a program of collectivisation of agriculture as the state combined the peasants' lands and animals into collective farms and enforced the policies by the regular troops and secret police. Those who resisted were arrested and deported and the increased production quotas were placed on the peasantry. The collectivisation had a devastating effect on agricultural productivity. As the members of the collective farms were not allowed to receive any grain until sometimes unrealistic quotas were met, starvation in the Soviet Union became more common. In 1932–33, millions starved to death in a famine known as Holodomor or "Great Famine". Scholars are divided as to whether this famine fits the definition of genocide, but the Ukrainian parliament and other countries recognise it as such.
The famine claimed up to 10 million of Ukrainian lives as peasants' food stocks were forcibly removed by the Soviet government by the NKVD secret police. Some explanations for the causes for the excess deaths in rural areas of Ukraine and Kazakhstan during 1931–34 has been given by dividing the causes into three groups: objective
