Here's something that hasn't really been talked about (or at least I havn't seen it...) It's the idea about some population of people migrating to another Civs country and joining the other city. You could do this with units, or have it just be a passive thing, but either way it would add a lot to the game, and its really realistic, especially in the modern times.
It'd add value to culture, and overall development of the Civs. Plus it could be a way to get rid of unhappy citizens, like how the loyalist fled the US when the revolutionary war happened.
