Single-Family Homes Are Back In Demand

Prior to COVID-19, the share of new housing units designated as single-family homes had been decreasing for decades. According to the U.S. Census Bureau, 71.5 percent of new housing units in 1990 were single-family homes. By 2019, however, only 62.2 percent of new housing units nationwide were single-family homes. Notably, the overall number of new housing units authorized dropped precipitously in 2008 during the Great Recession, and has still not recovered to pre-recession level.

As of the 2018 American Community Survey, approximately 67 percent of all existing housing units in the U.S. were categorized as single-family homes. But there is some regional variation, with 74.3 percent of existing homes in the West North Central Division and only 59.5 percent of existing homes in the Middle Atlantic Division designated as single-family. In most regions, new single-family home investment in 2019 lagged behind historical levels. Single-family homes accounted for a larger share of new, rather than existing, housing units in just two Census divisions, both of which are in the South.
