Overcrowded? Do you mean it's not happy or not healthy? For the former, build happiness (like temple), connect lux resource, or increase culture slider (after knowing drama); for the latter, connect health resource and build health buildings (like aquduct).
As far as I can tell, you don't. That's simply a mechanism for controlling city size. Every city gets a +1 unhealthy per pop point and a +1 unhappy, as well.
