Anchored in Milwaukee's urban core, this district delivered a 2.4-point Democratic presidential margin in 2024, making it one of the most lopsided state senate seats in Wisconsin and a reliable indicator of the city's dense, majority-minority precincts.
Across the recorded series it reached a Democratic high of 48.4 points in 1936 and a Republican high of 42.5 points in 1920. Between 2020 and 2024 the district moved 1.9 points toward the Democratic candidate; the 2024 margin was 2.4 points.
A population of 178,049, a 83% non-Hispanic-white share, and a median household income of $103,557 describe the district. The district's voting pattern over the last decade is most similar to that of State Senate District 5 and State Senate District 28.
