This documentary might help paint a picture even if it’s not your main source of statistics and such: The Human Face of Russia (1984) - society and everyday life in the 1980s USSR

The filmmakers are from Australia and they go to various places in the Soviet Union asking people about typical quality of life questions like price of rent, bus fare, work, having a look at farms, etc.

Marxism-Leninism and Nkrumahism by Kwame Ture

I recommend this 2016 documentary called Donbass by Anne-Laure Bonnel for some background on the issue
