The American birth rate is 1.8. The Russian birth rate is 1.6. Slightly less but Russia strongly supports families and doesn’t allow degenerates to groom its children.
“The American birth rate is 1.8. The Russian birth rate is 1.6.”
You’re neglecting to take into account immigration/emigration rates, which are the other major element of population trends (along with death rates, but those stay pretty stable most of the time). The US always gains population through immigration, while Russia has been consistently losing population due to emigration.
