The majority of the world raises their children in densely populated and compact cities. It’s not about partying, it’s about social exposure.

I grew up in a dense city outside the US, and even as a not-particularly-social child, I still had plenty of friends I played with and hung out with, and also had tons of interaction with adults. Meanwhile I’ve seen my cousins grow up in suburbs over the past 10 years, and they interact with maybe 3 non-family members outside of school, because everything is like a 15 minute walk away through winding suburb streets. That kind of isolation is not healthy at all.
