[Systemic33]

As many people have already said, the article seems to jump to a conclusion rather quickly.

What the author might not have taken into account is cultural changes in living habits. With that I mean how we are increasingly moving away from our parents home, and into our own little cell/room/apartment, instead of living with the parents in the house or in an attached building. And when people did move out, it would more than often be either because you moved into a dormitory (which previously were more communal) or together with a SO. That means more time spent in the neighbourhood, and more time with the middle ring as it's called in the article.

It could be interesting to compare the situation in america with for example the situation in Italy, where it's more common to stay at the parents for longer.
