This report by Up for Growth, a national network committed to solving the housing crisis, gives a data-driven look at housing underproduction and its consequences. In 2019, the housing crisis seemed to affect mainly the coasts and Southwest. Since then, it’s spread to encompass rural, suburban and urban areas in almost all states. The deficit in the number of new homes being built is driven by fewer households forming due to a lack of affordability, lack of supply and uninhabitable units. The nation was 1.65 million units short in 2012, which rose to 3.79 million units in 2019. Exclusionary zoning continues to be used as a way to keep Black people from buying a home; the rate of Black homeownership has barely budged since 1970. And a lack of affordability stymies personal income growth by limiting access to jobs.
