Description: Map showing the numbers and location of hogs produced in the United States in 1920. "Between 1910 and 1920 the number of hogs continued to increase in the Dakotas, but decreased notably in Kansas and Oklahoma, where war-time prices for wheat had caused it to supplant much of corn. In the western States, especially California, the number had increased; also in Alabama, Georgia, and the Carolinas."—United States Department of Agriculture Yearbook, 1923
