Washington DC is the seat of the federal government of the United States of America, and resides within a special federal district under the jurisdiction of the U.S. Congress, so it does not belong to any U.S. state. The many functions of the federal government and the private contracting industry that services its many departments make up a recession-proof local industry that carries on even during national and global economic downturns. Many defense and civilian contractors, law firms, non-profits, lobbyists, trade associations, and professional groups comprise this unique local economy and have their headquarters in Washington DC. Annually the gross domestic product of the greater Washington metropolitan area exceeds $430 billion, which makes it the sixth-largest metro by GDP in the United States.
