Still, I wonder how much square footage of housing was built; not just units. I'm under the impression that the average house built in the 10's era is larger than one built half a century before which could mean that more housing is being built (by area or volume) and yet fewer units are available. I guess I'm one of those anti-consumerist, people-should-live-in-modest-housing malcontents, but I grew up in a family of four in a small house, and we got by no problem.
