Wash DC is the richest zip code in the USA.
"Wash DC is the richest zip code in the USA."
Which Zip Code in DC are you alluding to? I thought the richest (wealthiest) zip in the US was in Northern Virginia - Great Falls (suburb of DC). The last I heard Fairfax County, VA was the wealthiest county in the US - includes both Great Falls & McClean (both my sons graduated from McClean HS).
Just doing a fact check. DC does have some very nice/wealthy neighborhoods, but not the size of Great Falls, or Potomac, MD.
