A lot of real estate is being built and most of it is "low cost" economy class, which in the end lets a lot of people who want that, own an apartment and have children. Home ownership statistics are also great.
The pay is meager but at least jobs are there, meaning that if you own an apartment or a house (often inherited from your ancestors in some form) and is employed, and can fall back to Babushkas' safety nest, you can have children and that will not ruin you. Also, actual child care benefits are fine. Long parental leave et all.
Russia also actually saw a lot of economic growth since both 1999 and 1991. Perhaps the most of all ex-USSR countries, save for Baltic states, but in case of Baltics there's a serious job crunch as far as I know. The pay is nice but securing it becomes a headache. In the end it's easier to move westwards.
I'm not sure why you would assume Russian outlook is particularly bad, especially if we're talking before the 2022. After 2022, too early to say.
