The thing that makes it hard is differing cultural standards between parts of the world. You either acknowledge them and push moderation decisions down as far as possible to local authorities, users, and group moderators or (what they seem to be doing) build an authoritarian, culturally-imperialistic global AI censorship algorithm that makes people mad and (hopefully) causes them to leave.

You're right as far as the post I replied to is talking about mortal health risk to mother or child, which doesn't seem to be a huge issue at 35. I was also thinking about the risk of not being able to have kids at all, or having less serious issues like Downs which is pushing 1% of live births before age 40 (https://www.aafp.org/afp/2000/0815/p825.html).

The fecundity of women decreases gradually but significantly beginning approximately at age 32 years and decreases more rapidly after age 37 years [1]. A woman over 35 is nearly 2.5 times more likely than a younger woman to have a stillbirth [2].

I see at least three distinct populations here. First are the Mormons of Utah, south Idaho, and adjacent areas, which you missed.

The big one is the Bible Belt minus the Black Belt, and also seems to be missing the Carolinas, maybe because they've had so much internal migration from the Northeast recently.

El Paso and surrounding area is surely associated more with the Rio Grande Valley of far south Texas than either of these two areas -- a culturally distinct area of Tejanos and more recent Hispanic immigrants.

I don't know what to attribute the area of lower-age married fertility in eastern CO + western KS to, or other scattered areas.
