Literacy rates in the Soviet Union in 1941 were much higher than they had been in 1924.
This was largely due to the wider availability of education in both urban and rural areas.
Whilst the quota system for entry into higher education had been abolished, there was still a much higher representation of working class people and women in higher education than ever before.
There was greater access to social services such as healthcare and nursery care.
The latter had contributed to more women entering the workforce although this was as much the result of economic necessity rather than the greater provision of childcare services.
Someone from a proletarian or peasant background could rise through the ranks of the party if they demonstrated some talent but mainly loyalty to Stalin and a willingness to carry out his orders.
