The U.S. Department of Commerce's Census Bureau released its quarterly report on residential vacancies and homeownership in December 2015. Data collected and analyzed by FindTheHome shows national vacancy rates for homeowner-occupied housing at 1.9%, otherwise known as the proportion of homeowner inventory which is vacant for sale. This is the same vacancy rate as posted by the Census last quarter, but an increase of 0.10 percentage points from the vacancy rate of 1.8% in June 2015. The homeowner vacancy rate reached a peak of 2.9% in March 2008.

The seasonally adjusted homeownership rate, which measures the proportion of total households that are owner occupied stood at 63.7% this quarter, showing a slight increase over the past two quarters after an all-time reported low of 63.5% in June 2015. Homeownership was as high was 69.4% in June 2004.

In this release, the Census reports that there are 1.45M vacant housing units for sale as of December 2015, compared to 1.42M last quarter and 1.46M this time last year.
