Highest-earning counties in Montana

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.

The 2023 real median household income in the U.S. was $80,610, an increase of 4.0% from 2022, the first statistically significant annual increase in real median household income since 2019.
