The population of Ukraine has decreased by 10 million people, or about a quarter, since the beginning of russia's full-scale invasion due to the departure of refugees, a decline in birth rates, and fatalities from the war. This was stated by the United Nations on October 22, as reported by Reuters.
Speaking at a Geneva news conference, Florence Bauer, Eastern Europe head at the UN Population Fund, said the invasion in February 2022 had turned an already difficult demographic situation into something more severe.
"The birth rate plummeted and is currently at around one child per woman, which is one of the lowest in the world", - she said. It takes a fertility rate of 2.1 children per woman to maintain a stable population.
Ukraine, which had a population of over 50 million when the Soviet Union collapsed in 1991, has, like almost all its Eastern European and Central Asian neighbours, undergone severe population decline. In 2021, the last year before russia's full-scale invasion it had a population of about 40 million.
Bauer said that a precise accounting for the impact of the war on Ukraine's population would have to wait until after the conflict ended when a full census could finally be carried out.
The immediate impact was on regions that were all-but depopulated, villages with only old people left, and couples unable to start families, she said.
