Definition matters. UN "Eastern Europe" = 10 countries above. Some definitions add Balkan states (Serbia, Croatia, etc.) → ~310M.
Russia spans Europe/Asia; ~77% of its population lives west of the Urals.
War impact: Ukraine's 2024 figure reflects ~6M refugees abroad + territorial losses; actual resident population uncertain.
Trend: Region declining 0.3–0.5%/yr (low fertility, emigration, aging). Russia's European part also declining.
