to ask for foreign aid for the famine and persistently denied the famine's existence. What aid was given was selectively distributed to preserve the collective farm system. Grain producing oblasts in Ukraine such as Dnipropetrovsk were given more aid at an earlier time than more severely affected regions like Kharkiv which produced less grain. Joseph Stalin had quoted Vladimir Lenin during the famine declaring: "He who does not work, neither shall he eat." This perspective is argued by Michael Ellman to have influenced official policy during the famine, with those deemed to be idlers being disfavored in aid distribution as compared to those deemed "conscientiously working collective farmers". In this vein, Olga Andriewsky states that Soviet archives indicate that the most productive workers were prioritized for receiving food aid. Food rationing in Ukraine was determined by city categories (where one lived, with capitals and industrial centers being given preferential distribution), occupational categories (with industrial and railroad workers being prioritized over blue collar workers and intelligentsia), status in the family unit (with employed persons being entitled to higher rations than dependents and the elderly), and type of workplace in relation to industrialization (with those who worked in industrial endeavors near steel mills being preferred in distribution over those who worked in rural areas or in food). Areas depopulated by the famine were resettled by Russians in the Zaporizhzhya, Donetsk and Luhansk Oblasts, but not as much so in central Ukraine. In some areas where depopulation was due to migration rather than mortality, Ukrainians returned to their places of residence to find their homes occupied by Russians, leading to widespread fights between Ukrainian farmers and Russian settlers. Such clashes caused around one million Russian settlers to be returned home. Ukrainians in other Republics Ukrainians in other parts of the Soviet Union also experienced famine and repressive policies. Rural districts with Ukrainian populations in parts of the Soviet Union outside of Ukraine had higher mortality rates in Russia and Belarus than other districts, this discrepancy did not however apply to urban Ukrainians in these areas. This is sometimes viewed as being connected to the Holodomor in Ukraine. In 1932–1933, the policies of forced collectivization of the Ukrainian population of the Soviet Union, which caused a devastating famine that greatly affected the Ukrainian population of the Kuban. According to the All-Union census of 1926–1937, the rural population in the North Caucasus decreased by 24%.
