Confirmed: Sprawl and Bad Transit Increase Unemployment [View all]

Since the 1960s and the earliest days of job sprawl, the theory of spatial mismatch that low-income communities experience higher unemployment because they are isolated from employment centers has shaped the way people think about urban form and social equity....
But its also been challenged. The research supporting spatial mismatch has suffered from some nagging flaws. For example, many studies focused on job access within a single metropolitan area, so it wasnt clear if the findings were universal. Other studies looked only at linear distance between jobs and low-income residents, not actual commute times. In addition, researchers including Harvard economist Ed Glaeser have argued that its difficult to determine whether neighborhood inaccessibility causes higher unemployment, or whether disconnected areas attract more people who have trouble finding work.
A new study (PDF) from researchers at the U.S. Census Bureau, the Comptroller of the Currency, and Harvard University, however, addresses those shortcomings and confirms the original theory of spatial mismatch: Geographic barriers to employment sprawl, suburban zoning, poor transit do indeed depress employment levels....
Black and Hispanic workers, women, and older workers were affected the most by spatial mismatch, the researchers found. While black people tend to live in neighborhoods with higher job accessibility by car, because they are more likely to live near downtown, researchers found that they are far more likely to rely on transit, which limited accessibility and put them at greater disadvantage.
