At roughly , it is the second-largest reservation in area after the Navajo, exceeding that of the seven smallest U.S. states (Rhode Island, Delaware, Connecticut, New Jersey, New Hampshire, Vermont, and Massachusetts). The seat of government is located in Durant, Oklahoma.

As of 2011, the tribe has 223,279 enrolled members, of whom 84,670 live within the state of Oklahoma and 41,616 live within the Choctaw Nation's jurisdiction. A total of 233,126 people live within these boundaries, with its tribal jurisdictional area comprising 10.5 counties in the state.

The Choctaw Nation is the third-largest federally recognized tribe in the United States, and shares borders with the reservations of the Chickasaw, Muscogee, and Cherokee, as well as the U.S. states of Texas and Arkansas. The original territory has expanded and shrunk several times since the 19th century, reaching its current boundaries in 1867. Provided by Wikipedia
