SP Group provides the U.S. Department of Housing and Urban Development (HUD) with analytic support services for the American Housing Survey (AHS). We study the changes in the characteristics of housing stock nationwide and summarize our findings in a report called the Components of Inventory Change (CINCH). Our study found that the total housing stock increased by 2.6 million units during 2015-2017.
For more information on the characteristics of the changes in the housing units and their occupants between 2015 and 2017, read our CINCH reports on HUD’s website.
