Arizona City is an unincorporated census-designated place (CDP) in southwestern Pinal County, Arizona, United States. It is located near the junction of Interstate 8 and Interstate 10 at the midpoint between Phoenix and Tucson, approximately 60 miles (97 km) from the downtown of both cities. The population was 10,475 as of the 2010 U.S. Census. It is estimated to be approximately 11,030 as of a 2017 U.S. Census estimate. Arizona City is a rural, primarily residential community that features a 48-acre man-made lake which has an HOA and is private to residents of surrounding homes only. These attributes make the community a popular snowbird destination, with the population increasing by as much as 5,000 people in the winter months to reach the census figure of 11,030. Most recently after the last Census, many full-time residents have relocated to the unincorporate town.
