For the second time in a week, Paul Krugman has written about sprawl. This time he is as wrong as the last, when he blamed Detroit’s bankruptcy on sprawl. Now he blames Atlanta’s entrenched poverty on urban sprawl. “The city may just be too spread out,” he says, “so that job opportunities are literally out of reach for people stranded in the wrong neighborhoods.”
Krugman quotes a study that finds that one of many factors reducing social mobility include “areas in which low income individuals were residentially segregated from middle income individuals.” But income segregation is very different from sprawl, and can take place in communities of any density. New York City, for example, has pretty high economic segregation.
Krugman adds that Atlanta’s sprawl “would make an effective public transportation system nearly impossible to operate even if politicians were willing to pay for it, which they aren’t.” He obviously doesn’t know the history of mass transit in Atlanta, which had a great transit system until regional leaders decided to build an expensive rail transit system. Since they aimed the rail lines at middle-class neighborhoods and sacrificed bus service to low-income neighborhoods to pay for the rail lines, transit’s share of commuting has fallen by more than 60 percent and per capita transit ridership has fallen by more than two thirds.
