LOOKING AT REAL AFFORDABILITY OF HOUSING.
"This map combines both housing and transportation costs. The result is maybe a bit surprising. In-city areas tend to look pretty good, while far-flung suburbs -- where you get a lot of square footage (and lawnage) for your money -- don't look so good at all. It makes a little clearer the tradeoff between floor space and travel costs, which tend to be higher than buyers imagine. Especially these days. In the maps below, the pale areas show places where housing transportation are 45 percent or less of median income. It's higher than 45 percent -- and therefore not "affordable" by this definition -- in the blue areas."
