Single parent homes

Robert Cherry has been analyzing the 2020 homicide rate, and finds three factors dominating: extreme poverty, fraction of the population that is black, and the fraction that is in single-parent with adult male head of household. We've known for a long time that single-parent is a problem, but that men should be so much worse at it than women is--maybe not surprising? Judges have been giving custody to women by default for a long time.

The summary didn't (and the data probably don't) provide a breakdown of divorced/never married, so I've no idea how many of these are abandonment and how many are a judge saying that the woman is really bad news. That might confound things slightly if "bad blood" is a real effect. But on the whole, the popular wisdom is probably right.
