Or it could be that the people who have more money, have less children.

I don't have real numbers, but it also seems like the very rich also have quite a few children. Super rich financial people in NYC have loads of kids, almost like a hobby. I've met super rich guys here who have 8 kids with 3 different wives. It seems to have a lot to do with whether or not your kids are going to effect you negatively economically. Super rich? Who cares... Super poor? who cares. Middle class or even sort of rich? Kids are going to make your life a financial headache.

I found some numbers to support and condemn my earlier statements.

http://www.russellsage.org/chartbook/householdform/figure4.5...

Shows that poorer households on average have more children. However, it also shows that that population is shrinking in unison. Relatively.

However, addition graphs on the website show how many dysfunctional households there are in poor communities. Which have been growing, so I stand by the original argument.
