Immigration?

[oogs]

I was wondering... when a planet is full of people (i.e. my homeworld with 4B people) is there any sort of immigration to other "available" planets, or do they.. uhh... just stop reproducing? If it isn't happening, I think that would be a good idea to include eventually because it would help system growth and be more realistic (c'mon, we can't expect 4 billion people to stop having sex!).

Just some thoughts
