When the Center for Neighborhood Technology released its revised Housing and Transportation Index last week, much of the focus naturally tilts toward cities due to the measurement of metropolitan areas. But CNT’s rural companion report on transportation costs in less-populated areas deserves ample attention as well. More than 1.6 million rural households do not have access to a car, making routine trips a strain on a family’s time and budget. For those who do drive, high gas prices take a big chunk out of monthly incomes.

Americans have spent the last several decades moving farther and farther away from urban centers, in search of affordability. Rapidly growing communities ranging from the sunbelt cul-de-sacs of greater Phoenix to the exurban fringes of Northern Virginia have sold people on a lower cost of living. The decades of “drive-til-you-qualify” resulted in millions moving out for supposedly cheaper housing. But was it actually more affordable? A new tool from CNT reexamines housing affordability.
