Median household income has climbed steadily in the United States since 2014, hitting an all time high of over $63,000 in 2018. In a country of over 330 million people, however, the national median income does not often reflect incomes at a local level — and how much you earn can depend greatly on where you live.
Median household income varies considerably from state to state — from as little as $43,600 in Mississippi to as much as nearly $82,000 in Maryland — and the difference can be even greater across communities and municipalities within states. For example, in every state, there is at least one county where the median income is higher than it is nationwide.
Using data from the U.S. Census Bureau, 24/7 Wall St. reviewed median household income in over 2,000 counties and county equivalents nationwide to identify the richest county in each state.
Many of the counties on this list — particularly those around major urban areas like New York City and Washington D.C. — have a high cost of living that necessitates higher overall incomes to some degree. However, the high incomes in these areas are also often attributable in part to the availability of jobs. In 49 of the 50 counties on this list, the unemployment rate is lower than it is across the state as a whole. Here is a look at the cities adding the most jobs.
Another factor contributing to higher incomes in the countries on this list is the skill level of the labor force. According to the Bureau of Labor Statistics, the typical worker with only a high school diploma earns $749 a week — about 71% less than the median weekly wage of $1,281 for those with a bachelor’s degree. All but three counties on this list are home to a larger share of college-educated adults than the state as a whole. Here is a list of the best-educated city in each state.

Methodology:
To identify the richest county in each state, 24/7 Wall St. reviewed median annual household incomes for each U.S. county using 5-year estimates from the U.S. Census Bureau’s 2018 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 have earned a bachelor’s degree or higher, poverty rate, and median home value from the ACS. Unemployment rates for October 2019 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. Alaskan Census areas, however, which are sparsely populated andare under the purview of the state government, were excluded.
