Title: Congressional Districts of the United States - 108th Congress
Abstract:: 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.

How should this data set be cited?

How were the data generated, processed, and modified?
Date: 16-Jan-2003 (process 1 of 3)
The spatial features of the National Atlas county boundaries layer (ATLAS-CNTY01) were compared against the State data sets and the Election Data Services data set to identify lines that were part of Congressional District boundaries. These lines were placed in a new file. In areas where there were no existing National Atlas features that were coincident with the Congressional District boundaries, the boundaries from the State data sets or the Election Data Services data set were extracted and added to the file. The list of members was updated with information for the 108th Congress from CD01_108.
