Re: your article. Who is having the babies? Who is replacing themselves? The big jump in child-bearing among 20-24 y.o.s - how is that demographic different than it was ten years ago?
“Who is having the babies? Who is replacing themselves? “
I don’t know the answer, but the article says:
“We do know that birthrates ticked up quite a bit among the most affluent,” says Stephanie Coontz, director of research and public education at the Council on Contemporary Families. “Kids are luxury goods, and some of this uptick may be stay-at-home moms.”
Thus, I don’t get the impression that the surge is among the least educated/intelligent in society. If the most educated were not replacing themselves, while the least educated were, then average education levels would be declining in the U.S. That is certainly not the case. You may argue that we send way too many people to college, but on average, the share of adults with college educations has risen steadily over time while the fraction with high school only educations has declined. These are encouraging trends from a Darwinian perspective.
