107th Congressional Districts

Congressional districts (CDs) are the 435 areas from which people
are elected to the U.S. House of Representatives. After the
appointment of congressional seats among the states, based on
census population counts, each state is responsible for
establishing CDs for the purpose of electing representatives.
Each CD is to be as equal in population to all other CDs in the
state as practicable.
The cartographic boundary files are a generalized extract from the
U.S. Census Bureau's TIGER database. Line simplification/smoothing
was performed with a tolerance of 0.005 decimal degrees and a
coordinate reduction using the Douglas-Peucker method with a
tolerance of 0.0003 decimal degrees. Very small polygons were
eliminated when the combination of geographic codes existed
elsewhere. The geography was clipped back to the shoreline of the
United States, in contrast to TIGER/LineŽ which shows the full
extent of geography out to the 3-mile limit.
These generalized cartographic boundary files are originally
produced to support the spatial geographic infrastructure
for certain mapping functions within the Census Bureau's
American Fact Finder and in support of the LandView
Geographic Data Viewer. The generalized files have a much
smaller file size than the original file extraction from the
Census Bureau's TIGER database, resulting in faster download
and processing times.
