Union Mill, VA

Union Mill is a census-designated place in Fairfax County, Virginia, near the outer edge of the Washington suburbs. It is not an incorporated town with a defined downtown, so the useful context is suburban: residential neighborhoods, county schools, local shopping, and road access toward Centreville, Clifton, and Fairfax. The name carries an older rural note, but modern Union Mill is best understood as part of Fairfax County's spread of commuter communities, with daily life tied closely to the larger Northern Virginia economy.
