The strongest predictor of how many children there are per woman is the average level of female education in a country - it’s an even stronger predictor than average income or anything on the men’s side of things. That’s why relatively poor eastern European and former Soviet block countries have low fertility rates more like those in wealthy western European countries than like similarly poor Latin American ones. Even though their average income is more like Mexico or Brazil’s, their average education level is more like England or Germany’s.
I bet in the US The strongest predictor is how seriously Christian they are!
Let me think of my church. Women who were married and are now past repro years - kids who weren’t miscarried or anything
Average 3.0. I was very scientific did the member ship roll and everything!
Married women in my church that have children so far that are still possible for more we have 9 kids for 6 moms bit that number likely to increase some are quite newly wed!
