United States Congressional Districts and Data, 1883-1913 is an atlas of U.S. congressional districts and almost 10 times the size of Rosenbach's effort and half a century longer in scope. It contains maps of all congressional districts during this period and includes the names and boundaries of all counties within each district. For metropolitan districts it often includes minor civil divisions such as towns, townships, and wards. In addition to the cartographic presentation of each congressional district, this work also presents key demographic data taken from United States censuses relating to each district and its constituent counties. This includes data on population, race, ethnicity, religion, occupation, and various economic variables. This is the third volume in a multi-volume reference work that will present demographic data from the United States census for each congressional district from the first congress in 1789 until 1956. Like its predecessors, United States Congressional Districts and Data, 1883-1913 will be particularly useful for studying legislative behavior and aggregate election analysis. It will be welcomed by researchers interested in these and other areas requiring U.S. census and congressional data.
