The Census Bureau treats independents citiessuch as Falls Church City, Va., and Fairfax City, Va.as counties, which is why they are included on the list.
This skews the entire dataset. It makes no sense to include cities in a county calculation. Not that DC isnt sucking wealth from everywhere else; but these rankings are completely invalid.
I have 2 cousins who live in Falls Church City and know that that isn't a county.
Cities in Virginia are independent entities, they’re part of no county.
In Virginia, independent cities are de facto counties. They have the same powers and responsibilities as a county.
