U.S. housing data

When I was in graduate school in the mid-1970s, one of my professors said there were about 60 million households in the United States. I became curious about how much we’ve grown since then and found the data below.

You can find this information and more at American Fact Finder, a service run by the U.S. Census Bureau. If you have time, play around with finding data. There’s lots of interesting information right at your fingertips.

The data set below is from 2011; it’s the most current available.
