My family is considered "underhoused" by the US government, because we have fewer bedrooms than occupants. I certainly don't feel it myself. We have three bedrooms for the four of us, and even chose to use the third as a media room until the kids get sick of the bunk beds.
I generally think that there's too much of a slant toward large houses in the new housing stock in the US, though - they're more expensive to buy and maintain, and generally not the best choice for young people.
