I'm not in the US, but can only think of one person in my rough age and social circle that is renting (and that was because he split with a partner and she bought his share of their house). Fairly middle class cohort, mix of public and private schooling. Average house price here is about $1m, though most would have bought earlier and cheaper.
Anyone younger and buying now would be up against it. I think housing affordability is one of the biggest issues we have.
I'm guessing that is location dependent, though it has changed recently, many people I've known (admittedly college educated or further, corporate tech) have been homeowners since their early-mid 20s. (millenial)
I guess it is this site but I always see SF Bay Area mentioned, everyone knows it is an outlier. Guess there's a lot of other cities in similar positions.
