NAHB Eye on Housing's Paul Emrath reports that 98% of of the 132.42 million homes that existed in the United States in 2011 were still there two years later, according to a recent report from the Department of Housing and Urban Development (HUD).

The report, called the Components of Inventory Change: 2011-2013, is based on the American Housing Survey, and is conducted in odd-numbered years by the U.S. Census Bureau. By revisiting the same housing units, it makes it possible to count how many homes were lost in between each survey. If past numbers remain consistent, they imply that half of the existing homes built 64 or more years ago will still exist 66 years from now. Additionally, half of the homes built recently will last for more than 100 years.

Of the 1,567,000 housing units lost between the 2011 and 2013 iterations of the AHS, 470,000 were due to demolitions and disasters, 212,000 were homes that became damaged or condemned, 202,000 involved putting existing homes to non-residential uses, 161,000 (primarily manufactured housing/mobile homes) were moved out from where they had been in 2011, 98,000 were due to conversions/mergers (e.g., a housing unit is lost when two smaller units are combined into a larger one), and 424,000 were units lost in some other way that fit none of these categories or couldn’t be determined. These statistics imply that 0.59% of the housing units in the U.S. are lost in a given year, but there are differences depending on the type of structure.
