More than half of the 390,000-plus households in Fairfax County (53.3 percent) have income of more than $100,000, according to 2011 American Community Survey data from the U.S. Census Bureau.

With a median household income of $106,000, Fairfax County is the second wealthiest county in the entire United States. Loudoun County was first with a median income of $119,000. Arlington County is third with a median income of $101,000, according to the 2011 data, WTOP reported.

The cost of living index in the Washington, D.C. metropolitan area is 139.2, or almost 40 percent higher than the average metropolitan area in the United States, according to  the Fairfax County Economic Development Authority. The index for housing costs is 222.7, more than twice the average for major metropolitan areas in the United States.
