"Figures for the population of Europe vary according to which definition of European boundaries is used."

But then, if Ukraine is already in Europe, that means I was double-counting when I added Ukraine, and the lower figure of under 200M applies. The "non-EU European population" component of that is from here: 94M. You can look up for yourself which definition of "Europe" that uses. If you're going to include Russia as far as Kamchatka in "Europe", well, why not include the whole world. Bosnia was a mere speck compared with six billion. "Never happened."
