(CBS) -- The number of people who live in their vehicles because they can't find affordable housing is on the rise, even though the practice is illegal in many U.S. cities.
The number of people residing in campers and other vehicles surged 46 percent over the past year, a recent homeless census in Seattle's King County, Washington found. The problem is "exploding" in cities with expensive housing markets, including Los Angeles, Portland and San Francisco, according to Governing magazine.
The problem of vehicle residency is national in scope, although its impact may be more "acutely felt in urban areas where space is more limited," said Sara Rankin, an assistant professor law at Seattle University and the director of Homeless Rights Advocacy Project, in an email to CBS MoneyWatch.
