Washington has long been a gateway for African Americans emigrating from the South, and since the 1960s has had a (now diminishing) black majority. Many citizens live in poverty, and social problems have been exacerbated by the transient nature of the governmental workforce and the District's lack of political power.
Transportation facilities include a subway system that connects the city with many suburbs. The main rail and air hubs are Union Station and Ronald Reagan Washington National and Dulles International airports (both in Virginia). Nearby military installations include Fort McNair, Fort Myer, Andrews Air Force Base, and Bolling Air Force Base.
