Although some mountain peaks receive an annual rainfall of more than 30 in. (76 cm), precipitation in most of the state is low, and much of Arizona's history has been shaped by the inadequate water supply. Since the early 20th cent., massive irrigation projects have been built in Arizona's valleys. Roosevelt, Horse Mesa, Mormon Flat, and Stewart Mountain dams, with reservoirs and storage lakes, irrigate the Salt River valleySalt River valley,
irrigated region around the lower course of the Salt River, which rises in mountain streams near the Mogollon Rim of the Mogollon Plateau and flows southwest to join the Gila River in S central Arizona. Phoenix is the main city of the latter Ariz. region.

The state's principal crops are cotton, lettuce, cauliflowers, broccoli, and sorghum. Cattle, calves, and dairy goods are, however, the most valuable Arizona farm products. Manufacturing is the leading economic activity, with electronics, printing and publishing, processed foods, and aerospace and transportation leading sectors. High-technology research and development, communications, and service industries are also important, as are construction (the state is rapidly growing) and tourism. Military facilities contributing to Arizona's economy include Fort Huachuca, Luke and Davis-Monthan air force bases, and the Yuma Proving Grounds. Testing and training with military aircraft and desert storage of commercial and military planes are both major undertakings.

Arizona abounds in minerals. Copper is the state's most valuable mineral; Arizona leads the nation in production. Other leading resources are molybdenum, sand, gravel, and cement.

The mountains in the north and central regions have 3,180,000 acres (1,286,900 hectares) of commercial forests, chiefly ponderosa pines and other firs, which support lumber and building-materials industries. The U.S. government owns about 95% of the commercial forests in the state. National and state forests attract millions of tourists yearly. Tourism centers in the N on the Grand Canyon, the Painted Desert, the Petrified Forest, meteor craters, ancient Native American ruins, and the Navajo and Hopi reservations that cover nearly all of the state's northeast quadrant. SE Arizona's warm, dry climate and Spanish colonial ruins also attract a large tourist trade, as do golf courses and other leisure facilities.


Between 1940 and 1960, Arizona's population increased more than 100%, and since then growth has continued. By the 2000 census the cumulative increase since 1940 amounted to more than 1000%, and Arizona was ranked among the fastest growing states in the nation. The mountainous north, however, has not shared the population growth of the southern sections of the state. Over 80% of the people are Caucasian and nearly 20% are Hispanic.

There were 203,527 Native Americans in Arizona in 1990 (or almost 6% of the people), the third highest such population in the United States. In addition to the NavajoNavajo

Government, Politics, and Education

The state's constitution provides for an elected governor and bicameral legislature, with a 30-member senate and a 60-member house of representatives. The governor and members of the legislature serve two-year terms. The state elects two senators and nine representatives to the U.S. Congress and has 11 electoral votes.

Republicans have dominated the politics of Arizona since the 1960s. In the late 1980s and 90s, political scandals tainted Arizona's governors. In 1988, Gov. Evan Mecham, charged with obstructing justice and financial improprieties, was impeached and removed from office. J. Fife Symington 3d, another Republican, won election in 1991 and was reelected in 1994; in 1997, convicted on fraud charges, he too resigned. Republican secretary of state Jane Dee Hull succeeded Symington and won election on her own in 1998. In 2002, Democrat Janet Napolitano was elected to succeed Hull. She was reelected in 2006, but resigned in 2009 to become Homeland Security secretary. Arizona's secretary of state, Jan Brewer, a Republican, succeeded her, and was elected to the office in 2010; Doug Ducey, also a Republican, was elected governor in 2014 and 2018.

Arizona's minerals, valued even by prehistoric miners, attracted most of the early explorers, and although the area remained a relatively obscure section of the Territory of New Mexico, mining continued sporadically. Small numbers of prospectors, crossing Arizona to join the California gold rush (1849), found gold, silver, and a neglected metal—copper.

The region had been held precariously by U.S. soldiers during the intermittent warfare (1861–86) with the Apaches, who were led by CochiseCochise

When Confederate troops were routed and Union soldiers went east to fight in the Civil War, settlement was abandoned. It was resumed after the war and encouraged by the Homestead ActHomestead Act,
1862, passed by the U.S. Congress. It provided for the transfer of 160 acres (65 hectares) of unoccupied public land to each homesteader on payment of a nominal fee after five years of residence; land could also be acquired after six months of residence at $1.

 and his brothers gained their reputations during the famous gunfight (1881) at the O. K. Corral. By 1880 the Santa Fe and Southern Pacific railroads both extended into Arizona. Ranching began to thrive and sheep raising grew from solely a Navajo occupation to a major enterprise among white settlers. After 1897, the U.S. Forestry Bureau issued grazing permits to protect public land from depletion.

In 1912, Arizona, still a frontier territory, attained statehood. Its constitution created a storm, with such "radical" political features as initiative, referendum, and judicial recall. Only after recall had been deleted did President Taft sign the statehood bill. Once admitted to the Union, Arizona restored the recall provision.

Modern Development

Irrigation, spurred by the Desert Land Act and by Mormon immigration, promoted farming in the southern part of the territory. By 1900, diverted streams were irrigating 200,000 acres (80,940 hectares). With the opening of the Roosevelt Dam (1911), a federally financed project, massive irrigation projects transformed Arizona's valleys. Although Arizona's mines were not unionized until the mid-1930s, strikes occurred at the copper mines of Clifton and Morenci in 1915 and at the Bisbee mines in 1917.

During World War II, defense industries were established in Arizona. Manufacturing, notably electronic industries, continued to develop after the war, especially around Phoenix and Tucson; in the 1960s, manufacturing achieved economic supremacy over mining and agriculture in Arizona. During the 1970s and 80s the state experienced phenomenal economic growth as it and other Sun BeltSun Belt

 served as secretary of the interior under presidents Kennedy and Johnson.

With the development of irrigation and hydroelectric projects along the Colorado River and its tributaries, water rights became a subject of litigation between Arizona and California. In 1963 the U.S. Supreme Court ruled that Arizona had rights to a share of the water from the Colorado's main stream and sole water rights over tributaries within Arizona. In 1968, Congress authorized the Central Arizona Project, a 335-mi (539-km) canal system to divert water from the Colorado River to the booming metropolitan areas of Phoenix and Tucson. The canal, which uses dams, tunnels, and pumps to raise the water 1,247 ft (380 m) to the desert plain, was opposed by environmentalists, who feared it would damage desert ecosystems. Construction was completed in 1991, at a cost of over $3.5 billion.

    state in the western USA. Area, 295,000 sq km; population, 1,665,000(1967). Administrative center, Phoenix.

    In the center of the state there are mountains with altitudes up to 3,861 m. The Colorado and Gila desert plateaus, dissected by rivers of the Colorado River basin, lie in the northeast and southeast respectively. The main branches of Arizona’s economy are irrigated farming (about 500,000 hectares [ha] in 1965) and mining. The primary agricultural crop is cotton (138,000 ha in 1965), which occupies about one-third of the state’s cultivated area. There is considerable cultivation of alfalfa and vegetables, and there are citrus orchards. Livestock raising is carried on mainly for the production of meat and wool (1, 116,000 head of cattle, 669,000 head of sheep in 1966). As small farmers have been dispossessed of the land, the number of farms has decreased from 18,500 in 1940 to 6,200 in 1965. The Hoover Hydroelectric Plant (Boulder Dam, capacity 1.3 million kilowatts), one of the largest in the country, is located on the Colorado River on the border with Nevada. Arizona holds first place in the USA in output of copper, with deposits at Miami, Bisbee, and Morenci. In 1965, 638,000 tons—56 percent of the entire output of copper in the USA—were extracted. Arizona also plays an important role in the mining of silver (171,000 kg in 1965) and gold (4,300 kg). There are factories for nonferrous metallurgy (smelting of copper and production of secondary aluminum in Phoenix, and others), for metalworking, and for the food industry. There are also rocket and radioelectronic industries. The state is a center for tourism: the Grand Canyon National Park is in Arizona.
