| Description | This compilation, a single, national-level synthesis in shapefile format of all changes in the size, shape, and location of every county in the U.S. (and their equivalents), from the creation of the first county in 1629 to 2000, provides a separate nationwide set of polygons for each date when a mappable boundary change occurred; changes dated to the day. Shapefiles are complemented by an attribute table with supporting information. The data are in the WGS84 geographic coordinate system. | |
