This article makes a lot of the "brain development" of people in their 20s. But that can't have changed too much over one or two generations, so I wouldn't look to it to try to explain why people in their 20s are taking longer to "grow up" than they did 50 years ago...
I think so much of this is just economic. My brother lived with a room mate until he was 34. He was an assistant professor at SF State, and his roomate was a high school teacher.
I know two men in their sixties (they are parents of my friends) who raised their children in San Francisco. They were... drumroll... a professor at SF state and a high school teacher. They both purchased houses in their late 20s/early 30s and got on with it.
Maybe the professions I've chosen are unrepresentative samples, maybe the city I live in is unusual for a high cost of housing... but in the early 70s, professors at state and school teachers could buy houses in SF. Now, they can afford to rent a 2br house with a roomate.
