In the US the nuclear family is usually two parents and two children. The parents share one bedroom and each child gets one.
In Asia I would guess families make room for their older relatives which would mean an extra bedroom is needed. Immigrants to the US typically do that but I think it's uncommon among the rank and file Americans.
