(CNSNews.com) - The five richest counties in the United States when measured by median household income are all still suburbs of Washington, D.C., according to American Community Survey data released today by the Census Bureau.

In fact, ten of the top twenty richest counties in the country are suburbs of Washington, D.C., according to this new data.

The same five suburban Washington, D.C., counties that were the richest in the country according to estimates that the Census Bureau released last year are also the five richest this year. However, their rankings have changed slightly in the new data release: Fairfax County, Va., and Howard County, Md., moved ahead of Falls Church City, Va.

According the American Community Survey’s new five-year estimates (2013-2017), the five richest counties in the United States when measured by median household income are: Loudoun County ($129,588), Fairfax County, Va. ($117,515), Howard County, Md. ($115,576), Falls Church City, Va. ($114,795), and Arlington County, Va. ($112,138).

In the five-year estimates released last December (2012-2016), Falls Church City ranked second and Fairfax County and Howard County ranked third and fourth.

The Census Bureau treats independent cities like Falls Church City as counties.

The other five D.C.-area counties that ranked among the nation's twenty wealthiest counties in the Census Bureau’s new data release were: Fairfax City, Va., which ranked No. 10 ($106,870); Montgomery County, Md., which ranked No. 17 ($103,178); Stafford County, Va., which ranked No. 18 ($103,105); Prince William County,Va., which ranked No. 19 ($101,059); and Calvert County, Md., which ranked No. 20 ($100,350).

The wealthiest county in the United States that is not a suburb of Washington, D.C. is Douglas County, Colo., which ranked No. 6 with a median household income of $111,154. Douglas County is south of Denver and north of Colorado Springs.

Three New Jersey counties made the Top 20. Hunterdon County was No. 7 ($110,969); Morris County was No. 9 ($107,034); and Somerset County was No. 12 ($106,046).

Three counties in the San Francisco Bay Area also made the Top 20. Santa Clara County was No. 11 ($106,761); San Mateo County was No. 14 ($105,667); and Marin County was No. 15 ($104,703).

Los Alamos County, N.M., which is home to the U.S. Department of Energy’s Los Alamos National Laboratory, was No. 8 ($110,969).
