Six of the richest U.S. counties are within commuting distance of the federal government's headquarters, according to an analysis of Census Bureau data by The Atlantic.

Meanwhile, the poorest 10 U.S. counties are far from Washington, D.C., the Atlantic reported Tuesday. The figures are in median household income dollars.

Another way of looking at the richest American cluster of counties that's around Washington, D.C., is to notice that the nation's wealthiest communities encircle the capitol. (Some rich counties, like Falls Church City, which is No. 1, are too small to appear easily.)
