@JKaorin yes! That's exactly the sort of tool I'm looking for! I like to see the neighborhood families also grow and develop, but since I've never been much of a rotational player (and play a vanilla game) I end up spending a lot of time visiting around and trying to make notes about who is in the same age group that I could pair up later, and who is at an age now where pairing up to make a new family unit makes sense and so on. I think I have way more young ladies, a lack of population balance, but unless I go and count household by household I can't be sure.
