In this report, we use the most recent data from the American Community Survey to investigate whether income segregation increased from 2007 to 2012. These data indicate that income segregation rose modestly from 2007 to 2012. This continues the trend of rising income segregation that began in the 1980s. We show that the growth in income segregation varies among metropolitan areas, and that segregation increased rapidly in places that experienced large increases in income inequality. This suggests that rising income inequality continues to be a key factor leading to increasing residential segregation by income.
