How do population locks on Continents work?

[Cease]

I mean whats the determining factors? Total population? Empire population?

[Bad Mojo]

AFAIK, pop-locks enforce a ratio of empires allowed on the continent up to the max allowed on the continent overall.

So, for example, if Cyssor can hold a total of 3000 people, and there are 50 VS and 50 NC, there's no poplock for anyone. But if there's 50 VS and 100 NC, the NC might be poplocked (until the VS or TR get close to 100 people on Cyssor). And if there's 1000 NC, 1000 VS, it's poplocked to NC and VS, but not TR.

Someone correct that info if it's not right.
