Metropolitan regions that are more equal and integrated with respect to income, race, and place are more likely to sustain economic growth over time, according to a study by the MacArthur Research Network on Building Resilient Regions. The study, Buddy, Can You Spare Some Time? Social Inclusion and Sustained Prosperity in America’s Metropolitan Regions, examines growth spells in the 184 largest U.S. metropolitan areas from 1990 to 2011 and finds that growth lasted longer in regions with less income inequality, less racial segregation, and less political fragmentation.
