Pima County /ˈpmə/ is a county in the south central region of the U.S. state of Arizona. The county is named after the Pima Native Americans which are indigenous to this area. The population was 980,263 at the 2010 census. The county seat is Tucson,[2] where nearly all of the population is centered. It borders between southwestern Arizona and northwestern Mexico's Sonora state. In 2015, the population of the county has been predicted to be 1,132,440. Pima County contains parts of the Tohono O'odham Nation, as well as all of the San Xavier Indian Reservation, the Pascua Yaqui Indian Reservation, Organ Pipe Cactus National Monument, Ironwood Forest National Monument and Saguaro National Park.

The vast majority of the county population lies in and around the city of Tucson (2011 city population: 525,796), filling much of the eastern part of the county with urban development. Tucson, Arizona's second largest city, is a major commercial and academic center. Other urban areas include the Tucson suburbs of Oro Valley (population 41,335), Marana (population 35,232), Sahuarita (population 25,458), and South Tucson (population 5,695), a large ring of unincorporated urban development, and the growing satellite town Green Valley. The rest of the county is sparsely populated; the largest towns are Sells, the capital of the Tohono O'odham Nation, and Ajo in the far western region of the county.

History[edit]

Pima County, one of the four original counties in Arizona, was created by the 1st Arizona Territorial Legislature with land acquired through the Gadsden Purchase from Mexico in 1853. The original county consisted of all of Arizona Territory east of longitude 113° 20' and south of the Gila River.[3] Soon thereafter, the counties of Cochise, Graham and Santa Cruz were carved from the original Pima County.[4]
