Pima County serves over 1 million residents across approximately 9,200 square miles in southern Arizona. Created in 1864 as one of Arizona's four original counties, it has grown from a population of 395 in 1820 to more than 980,000 residents as of the 2010 Census, with projections reaching 1.4 million by 2041. The County manages 50+ departments providing comprehensive government services, from public safety and health services to parks, libraries, and infrastructure development. As one of the oldest continuously inhabited areas of the United States, Pima County is home to the Tohono O'odham Nation - the second largest Native American reservation in the nation - and features remarkable ecological diversity with more than 400 bird species annually.
Pima County balances natural resource preservation with regional growth, having purchased thousands of acres to protect stunning landscapes and historic sites. The County created "The Loop," a 55-mile multi-use path system connecting diverse communities, and established dozens of parks and trails spanning from Mount Lemmon's 9,000-foot forests to lower desert mountain parks. Home to Tucson, Arizona's second-largest city and former territorial capital, Pima County hosts major attractions including Saguaro National Park, Kino Sports Complex, Pima Air and Space Museum, and the Arizona-Sonora Desert Museum. The County government employs thousands across classified and unclassified positions, offering long-term careers grounded in public service with comprehensive benefits including healthcare, retirement plans, and paid time off.
