Visualizing the 3 counties with the highest median household incomes in each state
The 2012 - 2016 American Community Survey, is a massive five-year study conducted by the U.S. Census Bureau. Among the data collected in this survey is the median household income for every county in the U.S.
Recently I dug up some data from this survey to find out which counties had the highest income in each state. In the map below, the three counties with the highest median household income in each state are shown in blue.
Hover over or click on individual counties to see their median household income, along with their population size.

Counties with Stories
It's fascinating to see what is considered a "high income county" from state to state. For example, the median household income in Loudoun County, Virginia is $125,672, which is more than double that of Maricopa County, the county with the highest median household income ($55,676) in Arizona.
It's also interesting to see how the location of these counties on the map indicate the type of economy that exists in that area.
For example, Los Alamos County, New Mexico has a median household income of $105,902 likely because it's the home of the U.S. Department of Energy national laboratory, which employs many scientists and engineers.
Another interesting spot on the map is Williams County, North Dakota, which has a median household income of $90,080 due the booming oil industry in that region.
Along the west coast the counties with the highest median household incomes are all located near major cities like Seattle, Oregon, and San Francisco.
Similarly, along the east coast the counties with the highest median household incomes are all located near major cities like Washington D.C., Boston, and New York City.
And among the states not located along the coasts we see that the highest income counties are near major cities like Minneapolis, Minnesota, Denver, Colorado, Chicago, Illinois, and St. Louis, Missouri.
