Zeihan claims Ukraine’s population has fallen 15% since the invasion began

What was said

""And so, we've seen a 15% drop in Ukraine's population just since the war began 4 years ago. There's very little reason to expect this war to be over soon, or if it ends in Russian victory, you know, none of these people are going to come back.""

Geopolitical analyst Peter Zeihan says Ukraine’s population has dropped by about 15% since Russia’s full-scale invasion began, attributing the decline to wartime outflows, particularly among women and families. He argues the loss could deepen if the war drags on, and says a Russian victory would likely deter return migration. Zeihan does not cite underlying demographic sources in the clip.
