Wisconsin Voting Districts Explorer

The Wisconsin Voting Districts Explorer provides interactive access to official U.S. Census Bureau voting district (VTD) boundaries for Wisconsin from the 2020 Census. This tool displays all precincts, wards, and election districts across Wisconsin, allowing election administrators, political analysts, redistricting professionals, and researchers to explore and download precise WI electoral boundary data.

Wisconsin’s voting tabulation districts represent geographic areas established by state and local governments for conducting elections and reporting vote totals. These WI precincts form the foundation of electoral geography, enabling precinct-level election analysis, voter outreach planning, and redistricting processes. Our map displays official National Geospatial Data Asset (NGDA) data updated weekly from the U.S. Census Bureau.

Understanding Wisconsin Voting Districts

Wisconsin voting districts, also called voting tabulation districts (VTDs), are the geographic areas used to administer elections and aggregate vote counts across Wisconsin. These WI precincts serve the fundamental purpose of organizing voters geographically for election administration and reporting precinct-level results.

The U.S. Census Bureau collected VTD boundaries from Wisconsin election officials and uses them to tabulate and report census statistics at the precinct level. This WI precinct data supports redistricting efforts for congressional and state legislative districts, enables demographic analysis of Wisconsin’s voting-age population, and facilitates election administration and planning throughout the state.
