What it would have done

Summary by the , the Legislature's nonpartisan drafting office. It's their wording, not ours.

This bill redistricts, according to the number of inhabitants, the legislative districts of this state based on the results of the 2020 federal decennial census of population. The bill maintains the number of assembly districts at 99 and the number of senate districts at 33. All assembly districts created by the bill are composed of whole counties or municipalities or U.S. census tracts or blocks (subunits of tracts) reflecting population and boundaries as of April 1, 2020. In accordance with article IV, section 5, of the state constitution, no assembly district created under the bill is divided in the creation of a senate district.

Current law requires legislative districts to be substantially equal in population. The table below illustrates, for the assembly and senate districts proposed under the bill, the numeric amount and the percentage by which the districts with the smallest and largest populations deviate from the ideal population for the same type of district. The population figures contained in the table are derived from the results of the federal decennial census.

Read the full summary

- See PDF for table The bill also requires the legislative reference bureau, in enrolling any redistricting plan that has passed both houses of the legislature, to attach an updated appendix that includes all of the following: the population statistics for the legislative districts created under the bill; a statewide map of the legislative districts created under the bill; a map of the legislative districts created under the bill that are in Milwaukee County; and, with certain exceptions, a detail map illustrating the division of any city, village, or town among two or more legislative districts.

For further information, see the appendix printed at the end of this bill. The appendix was prepared by the legislative reference bureau and contains the following information: population statistics for the 33 senate districts and the 99 assembly districts, a statewide map of senate districts, a statewide map of assembly districts (displayed over two pages), a map of Milwaukee County showing the assembly district boundaries in that county, and a map of Dane County showing the assembly district boundaries in that county. The population data contained in the appendix is derived from the federal decennial census.
