Highest-earning counties in Washington

The 2020 median household income in the U.S. was $67,521, a decrease of 2.9% from 2019. COVID-19 in 2020 drastically altered income and poverty levels, along with consumer habits and job opportunities.

Stacker compiled a list of the highest-earning counties in Washington using data from the U.S. Census Bureau. Counties are ranked by 2020 5-year estimate median household income.

Data shows that annual annual income depends heavily on an individual's educational attainment, race, ethnicity, gender, and even location. One cluster of the United States is particularly well off: The five of the seven counties with the highest median household income in the country can be found in the Washington D.C. metropolitan areas of Maryland and Northern Virginia. These counties can likely attribute their wealth to their proximity to Washington D.C., which attracts highly educated and skilled people in areas of law and public policy. And people in those fields often marry each other, making two high-earning households one very high-earning household.
