Housing units per person really has not moved much since 2000 either way. We're basically near the median for the 20-year period.

One big issue not stated in the graph however is that the amount of childless people and people living alone is up, so we require more housing to match changing preferences.
It's a shame we can't compare to 1920, 1950 or 1970.
We only started collecting information on housing in 1940 [1]. That's why household data only go back that far [2].

My wife and I are looking for a house, and the lack of options is extremely dispiriting.

1995 population was 266.6M. Today is 331.9M. That is growth of 65.3M
