According to data released by the Department of Commerce’s Census Bureau, the homeownership rate for the fourth quarter of 2010 was 66.5 percent, down from 66.9 percent in the third quarter. Homeownership peaked at 69 percent in 2004, at the height of the housing boom. Despite the drop, recent sales increases point to a possible rebound in the first quarter of 2011. Also in the report, the homeowner vacancy rate was 2.7 percent, unchanged from a year earlier and 0.2 percent higher than the previous quarter. More here and here.
