There are 3,144 counties and county-equivalents in the United States. The source of the data is the U.S. Census Bureau and the data is current as of the indicated year. Independent cities are considered county-equivalent by the Census Bureau.
Summary
Before the American Civil War, the wealthiest counties were primarily located in Louisiana and Mississippi, because of the high number of enslaved people, who were not included in the population.[1]
Loudoun County, Virginia, a suburb of Washington, D.C., is the highest-income county by median household income. Another Washington, D.C. suburb, Arlington County, Virginia, ranked as the highest-income county by median family income as of 2013.[2]
