One of the most prosperous countries in the world, the United States has built a reputation as the land of opportunity. While this may be an oversimplification, many affluent areas across the country serve as a testament to Americans’ continued ability to build wealth and financial stability.
In every state, there are counties or county equivalents where the median annual household income is well above the $62,843 national median. In over half of all states there is at least one county where the median annual household income is greater than $85,000. Using five-year estimates from the 2019 American Community Survey from the Census, 24/7 Wall St. identified the richest county in every state.
While there are several notable exceptions, many of the wealthiest counties in each state are part of, or in close proximity to, a major metropolitan area. Large metropolitan areas are often hubs of economic activity.
Hamilton County is located in central Indiana, just north of Indianapolis. By far the wealthiest county in the state, the median household income of $98,173 in Hamilton County is about $15,000 higher than the median income in Boone County, Indiana’s second wealthiest county, and $41,900 higher than the state median.
Many of the wealthiest counties nationwide are in close proximity to major cities, which serve as regional economic hubs. With access to jobs in Indianapolis, the unemployment rate in Hamilton County is just 3.3%, well below the comparable 4.9% state and 6.4% national jobless rates.
