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. 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.                   *Information from Columbia Encyclopedia, Sixth Edition
