I’m a gen Xer in the US. I and most of my peer group have our own places. The ones with good careers and stable relationships generally have houses in more desirable areas, but even folks with more blue collar or less fancy jobs have a place further out in the suburbs or have a small condo. The only younger people I know who own are either in a situation where they both make serious money (like doctors or do well tech), come from money or occasionally just make it happen with just serious hustle and grit (and even then, I’m amazed they can do it).
