I don't know about the sports. It's probably more serious now. Youth soccer is a whole thing that didn't exist at all when I was a kid. But lots of kids played Little League or basketball or football back then (1970s). "Travel" teams were probably not as common, but I was not a sports kid so I don't have a lot of direct experience. There were also swimming lessons, music lessons, Cub Scouts, a lot of other kids activities. It wasn't all just hanging out at home.
