Business Insider has named Rockville the 18th “richest suburb in America” in a list they released just two days ago.
In their list they wrote that they included parts of Potomac, Darnestown, and Travilah along with Rockville, which certainly increases the median household income and housing prices (listed at $198,651 and $900,00).
Nearby Fairfax Station (17) and Great Falls (8) in Virginia were also on the list.
