Where can I find a list of cities with population (cities - former union)?

Question

Database

Good time of the day!
We need data on the population in the cities of the former Soviet Union.
It would be nice with the purchasing power of the population, but, I think, this cannot be found.
According to the population, it turns out only manually through Wikipedia to pull out this information.
Advise or direct.
Thanks
