United States

The United States of America (USA), commonly known as the United States (U.S. or US) or America, is a country composed of 50 states, a federal district, four major self-governing territories, and various possessions. The four major territories are American Samoa, Guam, the Northern Mariana Islands, and the United States Virgin Islands. There are eleven smaller island areas without permanent populations: Baker Island, Howland Island, Jarvis Island, Johnston Atoll, Kingman Reef, Midway Atoll, and Palmyra Atoll. U.S. sovereignty over Bajo Nuevo Bank, Navassa Island, Serranilla Bank, and Wake Island is disputed.
