CONSTITUTION AND RESEARCH GUIDELINES:
COMMUNITY PROFILE: The Tohono O'odham Nation, "People of the Desert," have lived in the region for more than 10,000 years. The federally-recognized sovereign nation was greatly affected by the legacy of the 1853 Gadsden Purchase, which split their lands between the United States and Mexico. Twentieth-century federal policies of forced relocation moved numerous Tohono O'odham families outside of Arizona, yet many continue to live in the Sonoran desert of their ancestral lands. Prior to the 1980s, the Tohono O'odham were known as the Papago Tribe.
The Nation is comprised of four distinct segments. The largest of these (the Tohono O'odham Reservation) is located 63 miles west of Tucson, Arizona, and is more than 2.8 million acres. San Xavier, the second largest land base, is 71,095 acres. Smaller areas include the San Lucy District (near Gila Bend, AZ), and Florence Village (near Florence, AZ). The Tohono O'odham Nation is organized into 11 districts with Sells, Arizona, functioning as the Nation's capital.
The Tohono O'odham Nation operates a two-year accredited community college in Sells, Arizona, offering numerous degrees, certificates, and other credentials. Principal economic activities include tourism - most notably the Mission San Xavier del Bac - and three casinos. The casinos employ more than 1,200 Native American and non-Native people. The Nation also operates other facilities, such as the Tohono O'odham Utility Authority, Tohono O'odham Economic Development Authority, and the Tohono O'odham Gaming Enterprise.
According to the U.S. Census Bureau 2018-2022 American Community Survey, the population of the Tohono O'odham Nation Reservation and Off-Reservation Trust Land is 10,052. The following document provides a Census snapshot of the Tohono O'odham Nation with comparisons to the state of Arizona and the United States as a whole.
