What is Arizona?

Arizona is a constituent state of the United States of America. It is the country’s sixth largest state by area and became a state on February 14, 1912, the last of the 48 contiguous states admitted to the union. Arizona’s population is mainly urban, especially since urban and suburban areas began growing quickly in the mid-20th century. Phoenix, in the south-central part of Arizona, is both the state capital and its largest city.
