Covering an area of approximately 9,200 square miles, Pima County is located in southern Arizona and is one of the oldest continuously inhabited areas of the United States. Pima County is adjacent to six Arizona counties and shares 132 miles of an international border with Mexico. Native Americans have lived in this region from prehistoric times to the present, with the Tohono Oodham reservation the second largest in the nation. From a population of 395 in 1820, Pima County now has a population of slightly more than 980,000, by the 2010 Census count. Aside from our vibrant multicultural diversity, we're also unusual in that we're a very urbanized County, with more than a third of our population living outside of any incorporated cities or towns. The majority of residents live in the Tucson metropolitan area with other population centers that include Green Valley, Marana, Oro Valley, Sahuarita, South Tucson, Vail, and the sparsely populated towns of Ajo and Sells, the capital of the Tohono Oodham Nation. The population of Pima County is projected to reach 1.4 million by 2041.
