A recent study from the Center for Housing Policy shows that, for the third year in a row, working renters face increased housing costs. Using data from the American Community Survey (ACS) collected in 2009, 2010 and 2011, this paper shows that despite falling mortgage rates and home prices, more than one in four working renter households (26.4 percent) spent more than half of their income on housing in 2011. This paper asserts that some of the underlying causes of these trends result from a loss of work hours among low- and moderate-income households and rising housing costs for renters, while housing costs dropped for owners.
