2021 - 2022 LEGISLATURE
June 1, 2021 - Introduced by Committee on State Affairs. Referred to Committee
on State Affairs.
AB369,1,2 1An Act relating to: timeline for local redistricting in Wisconsin following the
22020 federal decennial census.
Analysis by the Legislative Reference Bureau
Under current law, local redistricting in Wisconsin occurs in three phases
following each federal decennial census. The process starts at the county level in
which counties must adopt tentative county supervisory district plans within 60
days after the official publication of the census data for Wisconsin, but no later than
July 1 following the year of the census—July 1, 2021, in the current redistricting
cycle. After counties adopt tentative county supervisory district plans,
municipalities then have 60 days in which to adjust ward boundaries as needed
based on the census. Once municipalities adopt new ward plans, counties then have
60 days within which to adopt final county supervisory district plans, and cities have
60 days within which to adopt aldermanic districts where applicable.
Under federal law, the U.S. Census Bureau must deliver census data to the
states for redistricting purposes no later than March 31 of the year following the
census—March 31, 2021, in the current redistricting cycle. However, due to delays
in the census process resulting from the COVID-19 global pandemic, it is anticipated
that Wisconsin will not receive census data based on the 2020 federal decennial
census until as late as the end of September 2021.
This bill does all of the following with respect to the local redistricting timeline
following the 2020 federal decennial census:
1. Provides that counties have until February 22, 2022, to adopt tentative
county supervisory district plans based on the 2020 federal decennial census.

2. Provides that municipalities may not adopt new ward plans sooner than
April 15, 2022, nor later than May 15, 2022. Under the bill, in adopting new ward
plans, municipalities must take into account any previously enacted congressional
or legislative redistricting plan based on the 2020 federal decennial census.
3. Provides, consistent with current law, that each final county supervisory
district plan adopted on the basis of the 2020 federal decennial census must be
adopted within 60 days after every municipality in the county adjusts its wards, as
specified above.
4. As a result in delays to the local redistricting timeline due to the delay in the
state's receipt of census data for redistricting purposes, specifies that city aldermanic
district plans adopted on the basis of the 2020 federal decennial census first apply
to the 2023 spring primary and election and that final county supervisory district
plans adopted on the basis of the 2020 federal decennial census first apply to the 2024
spring primary and election or the 2023 spring primary and election in those counties
that have provided by ordinance for staggered terms of office for county board
supervisors.
