To add to my previous comment. There's nothing about "the US" that makes precludes any of this. Lots of people chose to remain (or move back to) close to their families especially when they have kids on their own.

EG when we bought the house because it was closer to the in-laws, the previous owners were moving to SC to be closer to their family. It's just a decision you make or not bother to make.

And then to make an extreme point - before this I used to live in Hell's Kitchen in NYC. When I visit my old hood now, it's basically one continuous giant Grindr date going on. That was totally fine when I lived there as a single person but as a family person it would be a tough situation (e.g. businesses not geared to kids, most neighbors aren't parents - eg there was no kids in my old building). Now I live maybe 30 miles away and it's all parents all around me. The idea of "go where parents are" and "go where other young families are" is relevant to absolutely anyone in the world, so I don't understand why whether I live in the US is even a question?

I am in a suburb that's closest to NYC without being a part of the city.

Doesn't sound different than most of the neighborhoods in Brooklyn
