Population shifts and changes over time impact voting districts for counties, municipalities, and school districts. The release of each decennial Census documents these changes and may call for local governments to redistrict. Annexation for municipalities also creates the need for redistricting. Redistricting consists of modifying voting district/ward boundaries in order to balance the total population so that each district/ward has approximately an equal number of residents. Brown & Associates, Inc. can assist with the analyzation of voting districts to ensure compliance with the one-man/one-vote principle according to the Voting Rights Act of 1965.
