Description: Map showing the numbers and location of hogs produced worldwide in 1922. "The centers of densest hog production are the Corn Belts of the United States and Hungary, the potato and dairying belt of northern Europe, and China, where hogs are fed largely on waste products and barley. Little is known about hog production in China, and the figures used are only estimates. In the corn-growing regions of Argentina and southern Brazil the number of hogs is increasing. Hogs are not numerous in tropical countries, because such countries, as a rule, are not densely populated and have available the vegetable oils to supply the needed fats. Moreover, in the tropical and subtropical climates hogs suffer more from parasites and diseases than in temperate climates. Religion practically excludes hogs from India, Turkey, and certain other parts of Asia; also from parts of Africa."— United States Department of Agriculture Yearbook, 1923
