(Undated)  --  Some of America's biggest cities have the biggest gaps between rich and poor. 

A Brookings Institution report released Thursday shows income inequality is most glaring in the country's biggest city, the nation's capital and four other high-profile, high population centers.  Joining New York City and Washington, DC on the most unequal list are Atlanta, San Francisco, Boston, and Miami. 

The report says America's least unequal cities for income earners are Virginia Beach, Virginia; Arlington, Texas; Mesa, Arizona, Las Vegas; Wichita, Kansas, and Colorado Springs, Colorado.
