United States

The United States of America (USA or U.S.A.), commonly known as the United States (US or U.S.) or America, was a country primarily located in North America. It was a federation of 50 states, which also included its federal capital district of Washington, D.C., and 326 Indian reservations. The 48 contiguous states bordered Canada to the north and Mexico to the south. The State of Alaska was non-contiguous and lied to the northwest, while the State of Hawaii was an archipelago in the Pacific Ocean. Outside the union of states, the U.S. also asserted sovereignty over five major unincorporated island territories and various uninhabited islands. The country had the world's third-largest land area, second-largest exclusive economic zone, and third-largest population, exceeding 500 million.
