How we acquired the Congressional District Boundaries |
For the States that have more than one representative, the Census Bureau sent a letter to each Secretary of State requesting a copy of the State laws and/or applicable court order(s) for each State. Additionally, the States were asked to furnish their newly established congressional district boundaries and numbers by means of geographic equivalency files. All states submitted equivalency files because most of the redistricting was based on whole census blocks (with the exception of Indiana, Kentucky, Pennsylvania, and Wisconsin, whose boundaries do go through some census blocks. For further information on these blocks, please see the usernote at the bottom of the tables for these States).
The Census Bureau entered this information into its geographic database and then produced block equivalency files that depicted the newly defined congressional district boundaries and numbers. Each Secretary of State was furnished with a file and requested to submit corrections and certify the boundaries.
