Arizona's population lives primarily in urban areas like Phoenix, Tucson, Scottsdale, Tempe, Mesa, and Glendale. The state gained statehood in 1912 and its economy was historically driven by copper mining until the 1950s. Major geographic features include the Grand Canyon, Painted Desert, and Monument Valley.
