The Russian president has recently asked Russians to have three children , and offered a free house to those that do....so there seems to be a shortage of Russkies...!
The truth is that just about every nation in Europe has a very small birth rate and/or kids per couple.
In Eastern Europe it is the worst.
Like you said the Russians are rewarding couples who have more children. I think this is one idea Poland (and others) in Europe need to seriously consider.

According to the three different sources, Polands fertility rate is near the bottom (you will find other Eastern European nations there too). Personally I find this really disturbing.
Supposedly you need 2.1 Births per woman in Europe to keep sustained population.
Some type of reward would be nice.
