Lots of native Siberians and the Eastern Ukrainians, while the Holodomor was centralized to Ukraine it was not restricted to Ukraine itself. Meaning lots and lots of starving people that either fled or died. Also the Soviets were still doing purges throughout Siberia and the Far East because they were paranoid of a resurgent White or Black army which definitely didn’t help, also when I say purges I mean entire villages wiped out.
