How common is it for people in your social circle of relative/friends to own their homes? (What country btw?)

Okay I don't have friends to ask..., but I have relatives and a lot of my parents' friend circle and a lot of them apparantly own their homes... and apparantly there are a few that even own rental properties...

(USA, their social circle varies from Seattle, Boston, NYC, and Philly)

I'm with my parents and they own this house...
