Per Capita Income in the United States: 1880-1910

The data for this chart comes from a study by Alexander Klein, "Personal Income of U.S. States: Estimates for the Period 1880-1910," Warwick Economic Research Papers, no. 916, Department of Economics, University of Warwick, available on the department website at http://ideas.repec.org/p/wrk/warwec/916.html. It covers the entire United States and can be used for purposes that go well beyond the American West and the transcontinental railroads.
