Title
Atlas of Historical County Boundaries [United States] {1783-2000}
Description
A project of the William M. Scholl Center for American History and Culture at The Newberry Library in Chicago, the Atlas of Historical County Boundaries is a powerful historical research and reference tool in electronic form. The Atlas presents in maps and text complete data about the creation and all subsequent changes (dated to the day) in the size, shape, and location of every county in the fifty United States and the District of Columbia. It also includes non-county areas, unsuccessful authorizations for new counties, changes in county names and organization, and the temporary attachments of non-county areas and unorganized counties to fully functioning counties. The principal sources for these data are the most authoritative available: the session laws of the colonies, territories, and states that created and changed the counties., This dataset contains polygons representing the various historical configurations of state and territorial boundaries in the United States, from 3 September 1783 (the date of the signing of the Treaty of Paris) to 31 December 2000. These polygons were generated from the U.S. Historical Counties NAD83 dataset, which is turn was derived from the individual state files created by the Atlas of Historical County Boundaries project. The metadata for the individual state files provide a detailed description of the methodology used to research, plot, and digitize the historical county boundaries.
