During and after the Great Recession, three of the top-10 metros that saw the sharpest rise in very rich and very poor neighborhoods were in Florida, according to a study conducted by economists Sean Reardon of Stanford and Kendra Bischoff of Cornell and reported by Fusion staffer Rob Wile.

The authors looked at changes in family income within U.S. Census tracts between 2007 and 2012 to determine the extent of economic segregation. The larger the decline in middle-income neighborhoods, the greater the segregation. Overall, the U.S. saw a modest increase in economic segregation, coinciding with rising income inequality during the period.

Here are the top 10 metros that saw the sharpest rise in very rich and very poor neighborhoods:

  1. Cape Coral-Ft. Myers, Fla.
  2. Greenville, S.C.
  3. Provo-Orem, Utah
  4. Charlotte-Gastonia-Concord, N.C./S.C.
  5. Raleigh-Cary, N.C.
  6. Springfield, Mass.
  7. West Palm Beach-Boca Raton-Boyonton Beach, Fla.
  8. Phoenix-Mesa-Scottsdale, Ariz.
  9. Fort Lauderdale-Pompano Beach-Deerfield Beach, Fla.

10. Providence-New Bedford-Fall River, R.I.-Mass.
Segregation of affluence not only concentrates income and wealth in a small number of communities, but also concentrates social capital and political power,” the authors write. “As a result, any self-interested investment the rich make in their own communities has little chance of ‘spilling over’ to benefit middle- and low-income families.”
