Russia's natural population growth has been negative or flat since 2000, which means that overall deaths have outnumbered births. Only 1.27mn babies were born in Russia last year, the lowest number since 2000. The drop in the birth rate echoes the massive drop in the 1990s following the breakup of the Soviet Union
