The United States has the largest economy in the world with a GDP of over $23 trillion. Given its population of around 332 million, the United States also has one of the highest average incomes in the world with a GDP per capita of $69,287.54.
Given the growth in the US economy, US GDP per capita has increased over time. Whereas US GDP per capita was slightly under $24,000 in 1990, the metric was slightly over $48,000 in 2010. Given high inflation this year and continued expected productivity gains in the future, US GDP per capita will likely continue to increase in the future.
While the United States has high income per capita on average, some counties in the US have higher income per capita than other counties. Some counties in the US also have higher median household incomes than other counties.
One reason for some counties having higher median household incomes is that some counties are more urban where the costs of living are higher. Another reason is that some counties may have the government, a big company, or multiple big companies based there. Depending on the jobs that the government or the companies offer, the median incomes in the county could be higher.
If a big company hires a lot of people in a county and that big company pays very well, many other people in the county could benefit as the big company employees will likely spend more money in the county and increase incomes for others in the area. The big company could also potentially increase real estate prices in the county, which can potentially increase incomes as well. With higher home prices, consumers in the county might feel more confident and spend more. If they spend more, economic activity and incomes could potentially increase in the area.
The Wealthiest Counties in the US
Many of the wealthiest counties in the US are in either Virginia, New York, or New Jersey. Some counties in Virginia benefit from being close to Washington D.C. which is the capital of the United States.

Given it is the seat of the government, many leading companies also have headquarters near Washington D.C. which also creates a lot of high paying jobs. Some counties in New York and New Jersey benefit from being close to New York City, which has many well paying jobs given it is the financial capital of the West.
