Second, the Fort Belvoir officer corps. Lots and lots and lots of Commissioned officers and Senior NCOs live in the area ~ but otherwise are assigned at the Fort in the various things they do there ~ which are rather incredible. Many black people in the group.
Third, the African Africans. This area has been popular for African immigrants. I think we have folks from every tribe in Sub Saharan Africa. They own businesses and work in a variety of upscale service industries.
No, actually not many "Takers" there ~ mostly "Givers" and most being reasonably well educated. Do they vote Democrat? Maybe, but they also vote Republican ~ particularly the guys from Ghana and other parts of former British Africa.
ROTC is a big deal at Mount Vernon Highschool, and this is the ONLY highschool in Fairfax that regularly beats Alexandria's T.C. Williams highschool.
There are Hispanics ~ further up the highway for the most part. Housing down there in that precinct is not exactly cheap. Then there's a fairly large Thai community scattered around ~
This is all pretty typical of much of Fairfax county ~ just people from everywhere ~ and I mean everywhere!
You forgot the Muslims. The last time I was at Fair Oaks mall I thought I was at an Egyptian bazaar.
