After Ukraine declared independence from the USSR in 1991, Ukraine has been seeing their population decrease overtime as people are emigrating from ex-communist countries to search for better lives. In 2014, Ukraine went through a revolution that ousted pro-Russian president Yanukovych, which triggered the Russian annexation of Crimea and the Donbass revolt. In February 2022, Russia invaded Ukraine and the war is still going on today as of July 5, 2022, and the war started a refugee crisis with millions of Ukrainians fleeing from their country, thus causing a sharp decrease in population growth.
