Moravia is only slightly smaller than the PRK with a population of around 250 million, though with large swathes of desert, jungle, and highlands it's surprisingly urbanized. Also worth mentioning is that with a large dwarven population, the number is somewhat skewed. Dwarves (or at least the ones in my nation) basically age only half as fast as most humans. They're also bigger than humans in terms of weight and sometimes even height.

The Commonwealth isn't socialist in the sense that you're thinking; it has something of a plutocratic oligarchy that hold most of the political weight in the National Party (read: Fascist Party). Any move to become blatantly socialist would both rub against this oligarchy and get you accused of being a Communist, so naturally it wouldn't fly.

They do restrict a lot of imports and have goals of economic independence, and there may be a few state-owned corporations for transportation, utilities, weapon research and production, etc. But beyond that it's all free market.

The main reason that I describe the Commonwealth as a fascist state is because it's extremely nationalist and a dictatorship. There are elections, but aside from the National Party there are just a few minor coalition parties allowed to exist. No opposing parties or candidates are allowed, and nepotism is almost a requirement to receive a high office.
