Per capita income by county
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 slaves, who were not counted as part of the population.[1]
Loudoun County, Virginia, a suburb of District of Columbia, is the highest-income county by median household income. Another District of Columbia suburb, Arlington County, Virginia, ranked as the highest-income county by median family income as of 2013.[2]
Many of the top counties in the following lists are found in the Northeast Megalopolis, particularly in the Washington metropolitan area and the New York metropolitan area.
