Wisconsin Ward Level Redistricting Data

Following each decennial U.S. Census, Wisconsin municipalities are required to redraw their ward lines to account for changes in population over the previous decade. Wards (called "precincts" or "voting tabulation districts" in other states) are the administrative subunits that are aggregated into election districts of equal population. Wards are used as the building blocks for state assembly, senate and congressional districts.

The ward level data is arranged by county and is based on information submitted by each municipality in the state.  

Wards were formed by aggregating census blocks and reflect the population reported by the U.S. Census Bureau for the April 1, 2000, Federal Census of Population.

Summary data at the county and municipal level is available in "2000 Federal Census of Population: County and Municipal Totals". The publication also contains the names and populations of municipalities split by county lines.
