Phoenix, Arizona is a capital.
 Arizona is part of the Four Corners region with Utah to the north, Colorado to the northeast, and New Mexico to the east; its other neighboring states are Nevada to the northwest, California to the west and the Mexican states of Sonora and Baja California to the south and southwest
Arizona's population and economy have grown dramatically since the 1950s because of inward migration, and the state is now a major hub of the Sun Belt
