The demand for affordable housing is far outstripping production across the country—with the U.S. now at least 3.8 million homes short of meeting housing needs, double the number from 2012, according to a report from Up for Growth released this week. The report, Housing Underproduction in the U.S., finds a shortage of nearly 1 million homes in California alone, the largest gap of any state in the country. Texas (322,000 units), Florida (289,000 units), and New York (234,000 units) are the next closest states. “Four years ago, the nation’s housing affordability problems appeared to be concentrated along the coasts and in the Southwest,” the report concludes: “The crisis has deepened and is more widespread, affecting urban, suburban, and rural areas and profoundly impacting residents in nearly every state.” Take a look at these helpful tools for interacting with Up For Growth’s new data created by the New York Times and NPR.
