Gila River Indian Community

The Gila River Indian Community of the Gila River Indian Reservation is federally recognized tribe of Native Americans. The tribe controls the Gila River Indian Reservation, a reservation in the U.S. state of Arizona, lying adjacent to the south side of the cities of Chandler and Phoenix, in the Phoenix Metropolitan Area in Pinal and Maricopa counties. The reservation was established in 1859, and the Gila River Indian Community (GRIC) was formally established by Congress in 1939. This tribe has citizens who belong to two ethnic groups, the Akimel O’odham and Maricopa (Maricopa language: Piipaash). The O'odham language name for the community is Keli Akimel Oʼotham, meaning "Gila River People".

The reservation has a land area of 583.749 square miles (1,511.90 km²) and a 2020 Census population of 14,260. It is made up of seven districts along the Gila River and its largest communities are Sacaton, Komatke, Santan, and Blackwater. Tribal administrative offices and departments are located in Sacaton. The Community operates its own telecommunications company, electric utility, industrial park and healthcare clinic, and publishes a monthly newspaper. It has one of the highest rates of Type 2 diabetes in the world, around 50% of the population. The community voluntarily contributes to Type 2 diabetes research, having participated in many studies of the disease.
