Detroit's early carriage industry helped Henry Ford and others to make it the "automobile capital of the world." The Detroit region continues to be home to the major U.S. automobile manufacturers, but declines in the field have caused severe unemployment in the city and its environs, and government and the health-care industry now employ more people. In addition to the manufacture of motor vehicles and motor vehicle parts, Detroit makes steel, fabricated-metal, and paper products; food and beverages; and chemicals. There is printing and publishing, and extensive salt mines lie under southwestern sections of the city. Detroit is diverse ethnically, with an African-American majority and the nation's largest community of Arab Americans.
