I don't know Sweden and Norway well enough to comment. From my experience in other parts of Europe, the situation was more complex. In countries I've been in, that period coincided with a move from farms, where land was ample, to cities, which were cramped. Big family housing wasn't really available; those cities had apartments which simply didn't really support larger families. Cost wasn't so much an issue for having a cramped 2 or 3 bedroom in the sixties, but beyond that, you moved into ultra-wealthy territory. So I guess my question is whether you could write a little bit more about the Scandinavian countries. That's my own ignorance speaking. Japanese cities are super-cramped. I would not want a big family in Tokyo.
