The Washington Business Journal recently published a list of the 50 wealthiest Zip codes in the area. Virginia neighborhoods dominated, with 27 appearances, followed by Maryland’s 19 and DC’s 4. The rankings take into account household income, average net worth, home values, and the rate of increase of wealth.
Neighborhoods in Fairfax and Montgomery counties filled out the top 14 spots, until Loudon broke through at number 15. DC didn’t even appear on the list until number 18, and even then it was in Georgetown’s 20057 Zip code, home to the University—and only 33 households.
