Although Tennessee is now primarily industrial, with most of its people residing in urban areas, many Tennesseans still derive their livelihood from the land. The state's leading crops are cotton, soybeans, and tobacco; cattle, dairy products, and hogs are also principal farm commodities. Tennessee's leading mineral, in dollar value, is stone; zinc ranks second (Tennessee leads the nation in its production). Industry is being continually diversified; the state's leading manufactures are chemicals and related products, foods, electrical machinery, primary metals, automobiles, textiles and apparel, and stone, clay, and glass items. Aluminum production has been important since World War I.
Tennessee has long been a major tourist destination, owing largely to its beautiful scenery. Many lakes were built here by the Tennessee Valley Authority (TVA) and the Army Corps of Engineers. The TVA also developed the Land Between the Lakes, an enormous Kentucky-Tennessee recreation area. Visitors are also drawn by Tennessee's famed music capitals, the country-music mecca of Nashville and the blues and jazz hub of Memphis.
