Which Metro Area Boasts 7 of the 10 Most Affluent Counties in America?

While communities across America have suffered through high unemployment, public sector cuts from dwindling revenues, and foreclosures resulting from the Great Recession, the Washington D.C. metropolitan area has been getting increasingly affluent. New census numbers show that the D.C. suburbs now include 7 of the 10 most affluent counties in the country, with Loudoun County and its median household income of $119,134 topping the list, report Carol Morello and Ted Mellnik.

"The rankings in the 2011 American Community Survey released Thursday expand Washington's dominance among high-income households, reflecting a regional economy that was largely cushioned as the recession yanked down income levels elsewhere. Household incomes rose in most counties around Washington last year, even as they continued to sink around the country."

Hunterdon and Somerset Counties in New Jersey, and Douglas County in Colorado, were the non-Washington area counties to make the top 10.
