1 Oklahoma tribal statistical areas (OTSA) are statistical entities identified and delineated by the Census Bureau in consultation with federally recognized American Indian tribes in Oklahoma that do not currently (2009) have a reservation, but once had a reservation in Oklahoma. Names of tribes in table are from the Census Bureau.
2 Joint use area OTSAs are lands that are administered jointly and/or are claimed by two tribes and are treated as if these areas are separate American Indian reservations for statistical purposes by the Census Bureau.
3 Reservations (Federal) are areas that have been set aside by the United States for the use of tribes, the exterior boundaries of which are more particularly defined in the final tribal treaties, agreements, executive orders, federal statutes, secretarial orders, or judicial determinations.
