This is somewhat old news but still seems worth mentioning. Newsweek has identified HoCo as the third richest county in the U S of A with a median household income of $101,940.
Perhaps the bigger story is that four of the top ten richest counties were in Maryland and three, including the top two, were in Northern Virginia .
Despite this ranking we still seem to have an easier time attracting retailers like Big Lots instead of a Crate & Barrel.
