I'm just stealing all the good ideas from Dominions 2, but hey, that's how games work, right?
So anyway, this idea from Dom2 is that while it makes sense for troops on a planet to increase productivity by "coercing" the population to work, they should also (for most happiness types) DECREASE reproduction, or even cause a small loss of population if there is no reproduction... think about it in the real world... people who are oppressed are not going to be wanting to bring up kids into their world, and there's always the occasional fatality from police brutality or mishaps or something
