I remember reading during the last years of the USSR, birth control was so unreliable (rumored to be so because white Russians were outnumbered and women could not be bribed to have enough babies to even up the numbers) that the average young Russian of a certain age had probably had 4 or 5 abortions. (even if married or in a long-term relationship). Because they had no food to feed that extra mouth.

Don't know if those numbers have ever been pinned down.
