The Gila River Indian Community is an Indian reservation in the U.S. state of Arizona, lying adjacent to the south side of the city of Phoenix, within the Phoenix Metropolitan Area in Pinal and Maricopa counties. Gila River Indian Reservation was established in 1859, and the Gila River Indian Community formally established by Congress in 1939. The community is home for members of both the Akimel O'odham (Pima) and the Pee-Posh (Maricopa) tribes.
The reservation has a land area of 583.749 square miles (1,511.90 km2) and a 2000 Census population of 11,257. 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 telecom 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 has voluntarily contributed to Type 2 diabetes research, by participating in many studies of the disease.
