Dear PoP – Does Columbia Heights Have The Highest Concentration of Peace Corps Volunteer Alumni?

Peace Corps. Poster, originally uploaded by Jrish85.

“Dear PoP,

Columbia Heights and/or the zip code 20010 has the highest concentration of former Peace Corp Volunteers than any other part of the US/World.

I can’t remember where I heard it, but now a friend of mine is asking if there is a source other than myself as to the validity of this claim. Would you or any of your readers be able to help point to some source that could confirm/deny this?”

I’m sure there are some former peace corps folks out there. Can anyone confirm this?
