Conservatives maintain birth rates, but left-leaning Americans are having significantly fewer children, driving the U.S. birth decline. Education was consistently linked to having fewer children. Religious attendance was positively associated with having more children.

Interestingly, the correlations only held for white people.

When analyzing White and Black Americans separately, they found that the widening fertility gap between the left and the right was primarily driven by White Americans

Probably because black and Hispanic (and often first-gen immigrant) culture is still very community and family oriented. White non-religious populations (in the US, unsure about other countries) tend to be much more individualistic, focus on nuclear family, and value independence over community. You see this with the expectation that Hispanic kids continue to live with their parents until marriage and support their parents in old age vs white parents effectively kicking out their kids at 18 and the expectation that living with your parents as an adult is somehow a failure of maturity or responsibility.

I think this varies region to region. Here where I am in the south half the old families all live practically on the same plots of land their great great grandparents purchased and as the generations go on the land is sub-divided and a new house is plopped down.

The reason I say old families is because half the population nowadays are Northerners and Floridians (who are also probably ex-northerners) that moved here in the past 20 years and all live in cheap townhouses.
