What is the Richest County in the US?

Money isn't everything. However, the wealth level of an area does impact the people who live there. Economists, public health and public policy officials often break down populations by their relative wealth to understand more about their needs or potential health risk factors. Sometimes that means that officials measure the wealthiest or poorest areas, either by zip code, city, town, or county. With more than 3,000 counties in America, there's a lot of competition for which county is the richest in the U.S.

How is Wealth measured by County?

Wealth is typically measured by looking at the median household income in each county. The median is the middle value in a set of values. Imagine all incomes are lined up from smallest to largest. The median would be the value that falls right in the middle of the list. This is different from the average. In income data, the average can be misleading, since a few very high earners in one spot could artificially inflate the number.

What is Per Capita Income?

The other way to measure wealth by area is by measuring the per capita income. The per capita income is the average income for an area. Per capita income is a useful way to measure income, but it is better for larger populations. In big groups, outliers with very high or very low income are less likely to sway the figure in one direction or the other.

What Does it Mean if You Live in a Wealthy County?

People who live in wealthy counties are more likely to live longer and have higher education levels. Just because a county is rich, though, doesn't necessarily mean that its state is rich. Although Virginia has quite a few wealthy counties, the income levels in the other counties are lower than average, so Virginia is not at the top of the list of wealthiest states.

08

What Does it Mean if You Live in a Poor County?

McCreary county's life expectancy is much lower than the national average. That's because poor health outcomes are more common in poorer counties. People in poorer counties often have a lower life expectancy and less education. Poorer counties also have higher unemployment rates, and people there are more likely to live below the poverty line.

09

Which State Has The Highest Number of Wealthy Counties?

On the list of 25 wealthiest counties, Virginia and Maryland both have five. Although these counties have high earners, they're not necessarily the highest earners. These counties have a high number of federal workers, lobbyists, defense contractors, and computer engineers that work with the government. Their salaries drive the median income figures that make these counties so wealthy.

10

Which State is the Richest State?

The richest counties aren't necessarily in the richest states. The wealthiest state in the U.S. is Maryland. Maryland is tied with Virginia for the highest number of wealthy counties, but Virginia is much lower on the list of wealthiest states, at number nine. The poorest state in the U.S. is Mississippi.
