More than 150,000 U.S. families are homeless each year. The number has been going down, in part because of a program known as rapid rehousing, which quickly moves families out of shelters and into homes.
But new research by the Obama administration finds that for many families, rapid rehousing is only a temporary fix.
It seemed like a good idea back in 2009 — when the recession had pushed thousands of families into homelessness.
