Where Are the Richest American Counties?

Loudoun County in Virginia is the U.S. county with the highest average wage earners. The median household income in Loudoun County is $125,672. That is over twice as much as the American median household income, which the U.S. Census Bureau reported in September 2017 as being $59,039.

Recently there have been a number of mapped visualizations of data from the American Community Survey (ACS). Maps Mania has already featured Bloomberg's interactive map of Neighborhoods Earning Over $200,000. In December we also linked to the American Ancestry map, which shows the most populous ancestry, Hispanic or racial group in each census tract based on ACS data.

Four Pillar Freedom has now used median income data from the 2012-2016 American Community Survey to map the 3 counties with the highest median household incomes in each state. The three richest counties in each state are colored blue on the interactive map. You can also hover over any county on the map to view the median household income in the area. Beneath the interactive map Four Pillar Freedom has also listed the three richest counties and graphed the median household incomes in each state.
