Most of our populations stayed at around 5 mil for months in Anagaea. We didn't accurately portray growth. With the amount of land Erinaum has, I could probably fit 2 bil comfortably.
You're saying that you could fit 6 billion in that space and be a self-sustaining country? I find that hard to believe. When you have countries that large, republics cannot run them because actions would be too slow. India is the largest republic to date, with 1.2 billion. I doubt that 4-6 billion would work with any system, let alone fit in Avalonia comfortably. Just look at China. You'd be buying so many goods from other nations that you'd be at a very unstable economic standpoint.
Calling Bullstuff. You jumped 300,000,000 in one instant. I don't care what you say. This is god-modding.
Avalonia isn't a republic, first of all (where on Anagea did you get the impression it was?). Secondly, your population didn't exactly creep up to what is it now? 300, 400 million? When did I say I was fully self sufficient, and either way, I could be if I chose because I have enough land to support a solid population's necessities, economic strength, and industrial improvement.
Since I won't be having any dealings with you I'd say it's wise to shut your trap since it doesn't concern you either way.
