First and most importantly, adjust for average income levels. Then, factor in transportation costs. Using that formula, the D.C. region is tops among 25 American metro areas in a new study from the Center for Housing Policy and the Center for Neighborhood Technology that looks at the ability of moderate-income households to shoulder the burden of housing and transportation costs [PDF]. The notoriously pricey Boston and San Francisco also make it into the top six.
The joint study came up with some other surprising findings. For example, it turns out it’s more affordable to live in New York City than it is to live in Cincinnati, based on the metrics used. And in general, renters fare better than homeowners in covering their costs of living.
In all 25 cities, middle-class households spent more than half of their incomes on combined housing and transportation costs between 2000 and 2010. Miami had it worst, with housing and transportation eating up 72 percent of the average income.
The study, titled “Losing Ground,” focuses on the disparity between income levels and steadily rising housing and transportation costs. Over the decade, researchers found, for every $1 in income gains, combined housing and transportation costs rose $1.75.
“Losing Ground” follows a 2006 study from the same organizations that took the novel approach of factoring in transportation costs to gauge the affordability of different metro areas. Measuring affordable living by looking strictly at housing costs, without including transportation, “tends to mislead people,” said Scott Bernstein, president of the Center for Neighborhood Technology, in a teleconference yesterday. Gathering this information comprehensively, he said, “has profound implications for a set of policy choices.”
