If the Russian Empire was able to survive until the 1990s at the earliest, how would the demography of the empire look? With Russia itself, I heard 200 million as of the year 2000 and Ukraine and Belarus maybe 60 and 15 million respectively. I'm thinking roughly these borders (minus Kaliningrad) as the minimum, what does the demographics and economics of Russia look like with the borders of today's Russia, Ukraine and Belarus? What would be the largest cities? Could it be successful?
