The Richest County in Every State


To identify the richest county in each state, 24/7 Wall St. reviewed median annual household incomes for each U.S. county using five-year estimates from the U.S. Census Bureau’s 2019 American Community Survey. We only considered counties with income estimates with a maximum 10% margin of error. 

We also reviewed in each county the percentage of adults who hold a bachelor’s degree or higher, the poverty rate, and the share of households earning $200,000 or more from the ACS. Unemployment rates for November 2020 are from the Bureau of Labor Statistics and are not seasonally adjusted.

County equivalents, such as parishes in Louisiana and boroughs in Alaska, were included in our analysis.
