Summary
Description
This map layer portrays the Congressional Districts of the United States for the 108th Congress. Lines coincident with Congressional District boundaries were extracted from the existing National Atlas County Boundaries layer. In areas lacking coincident geometry, lines from State data sets or from an Election Data Services data set were integrated into the file. This is an update of the March 2003 map layer.
