Arizona was the 48th state to join the United States, gaining statehood in 1912; it was also the last of the contiguous states to do so. The desert is the prevailing climate in the state’s southern region, with mellow winters and sweltering summers. The north of Arizona is covered with pine forests, mountains, and canyons. The Grand Canyon National Park, one of the world’s seven natural wonders, occupies a large part of this area.
Arizona’s population is above 7.3 million, the 14th most populous, and the 5th largest of all 50 states. Historically, Arizona relied its economy on the famous five C’s: copper (as in mining), cattle, citrus, cotton, and climate (as in tourism). Almost a quarter of the state’s surface comprises of Indian reservations, including the Navajo Nation, the largest in the country.
