Ukraineâs population is approaching 20 million, Ukrainain economists point out. Before the full-scale Russian invasion it was still 34â37 million, acc. to the talks in the Zelenskyy's office. About 10 million remain abroad, hundreds of thousands more live under occupation and are no longer counted in Kyiv, and at home roughly four people die for every child born. Territory can still be returned through diplomacy. The dead cannot, and neither can the children who were never born.
