In Denmark for many people it goes the other way. Suburbs are nice when you're a couple, because you've got a big yard, lots of space, etc. But once you have kids, they can become more of a hassle. Now you have to drive the kids everywhere. Many people prefer to live in the city (or one of the inner suburbs) once they have kids of a certain age, because then the kids can get around on their own, on bike or transit, rather than the parents having to drive them to/from every single thing. Kids also tend to prefer this, because it gives them more mobility/independence.
