Oklahoma Tribal Statistical Area


Oklahoma Tribal Statistical Area is a statistical entity identified and delineated by federally recognized American Indian tribes in Oklahoma as part of the U.S. Census Bureau's 2010 Census and ongoing American Community Survey.
Many of these areas are also designated Tribal Jurisdictional Areas, areas within which tribes will provide government services and assert other forms of government authority.
They differ from standard reservations, such as the Osage Nation of Oklahoma, in that allotment was broken up and as a consequence their residents are a mix of native and non-native people, with only tribal members subject to the tribal government.
At least five of these areas, those of the so-called five civilized tribes of Cherokee, Choctaw, Chickasaw, Creek and Seminole, which cover 43% of the area of the state, are formally recognized as reservations by federal treaty, and thus not subject to state law or jurisdiction for tribal members.
