Since the 1950s, Arizona’s population and economy have grown dramatically because of migration into the state, and it is know as the Sun Belt. Cities like Phoenix and Tucson have developed into large, suburban areas. Many large companies, such as Petsmart and CircleK have headquarters in the state, and Arizona is home to University of Arizona and Arizona State University.
