The county seat is Tucson, where nearly all of the population is centered. The county is named after the Pima Native Americans who are indigenous to this area.
Pima County comprises the Tucson, AZ Metropolitan Statistical Area.
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.

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.
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. Soon thereafter, the counties of Cochise, Graham and Santa Cruz were carved from the original Pima County.

Sonoran Desert Conservation Plan
The award-winning Sonoran Desert Conservation Plan (SDCP) is Pima County’s plan for balancing the conservation and protection of our cultural and natural resource heritage with our efforts to maintain an economically vigorous and fiscally responsible community. Broadly defined, the SDCP considered the following elements: critical habitats and biological corridors, riparian areas, mountain parks, historical and cultural preservation, and ranch conservation. All five elements, along with fiscal analysis, were critical in forming a viable land management plan for Pima County.
