In all likelihood I'll probably be basing my population off of Moravia's.

Having much more land than Zenovia, more infrastructure developed than pretty much anyone over the past two centuries, and having a history of centuries of prosperity (although plenty of war to prevent the population from exploding too much) makes me think that the Commonwealth would almost certainly be far larger than Zenovia. Really, the PRK is the only nation that I can see having reason to boast a bigger population, and even then if it's like its real world parallel the USSR, then it's surprisingly rural and low in population for its size whereas Moravia is somewhat dense in a lot of parts.

That's not counting fairyland of course, with SEVEN BILLION people :arghfist
