The bursting of the housing bubble pushed the U.S. economy into recession, and continued weakness in housing has been a stubborn obstacle to a faster recovery. Recently, though, there are signs of improvement. A key measure of home affordability has gotten better—suggesting demand might start to pick up fairly soon—while the inventory of homes languishing on the market has shrunk.
Affordability is measured by a monthly index produced by the National Association of Realtors. An index reading of 100 means a family with a median level of income has just enough income to qualify for a median-priced single-family home (assuming a 20 percent down payment). As the chart shows, affordability began declining in the first half of the 2000s, just as inventory started to soar.
