DENVER (KDVR) — A new report ranks one Colorado county among the richest in the country.

Five-year U.S. Census estimates show that 49 counties in the country have median household incomes higher than $100,000, according to U.S. News & World Report. Of those, the top 15 are concentrated on the coasts among the areas of Washington, D.C., San Francisco and New York City.

But one county in New Mexico made the list, and so did one in Colorado: Douglas County.

People are flocking to the south metro county, and they’re bringing high incomes with them. Douglas County ranked ninth nationwide, with a median household income of just under $120,000.

While recent data suggests more people are moving out of the Denver metro than are moving in, Douglas County is experiencing the opposite. More than 7,500 people moved into Douglas County than left in 2021, according to a FOX31 Data Desk analysis. The suburban county grew by nearly 25 people a day last year.
