In the past year, Russia had its most significant peacetime population decline of all time.
Since last October, Russia's natural population has declined by 997,000, according to The Washington Post. The natural population is determined by the difference between the country's death rate and birth rate.
"[The] overwhelming share of this decline is associated with an increase in mortality, which is also reflected in the dramatic drop in life expectancy that fell by about 4 years," Alexey Raksha wrote in a Facebook post about the change, per the Post. "In turn, an overwhelming share of this increase in mortality is due to Covid-19."
