People who want to have children should have them, and people who don't want to have children shoudln't have them =)
Simply compare the two curves. Those with children vs those without.
Your comment stands if you look at outliers, GP stands if you take the curves.
Would that be bad? How?
And you are adding other factors if you think people who do not want kids are somehow the outliers. Same as if people wanted kids might be if you actually looked closely, for most people its not a very well thought out choice.
