[1] Located in northeastern Wisconsin, the district comprises all of Door and Kewaunee counties, as well as portions of northeast Brown County.

[2] The district is represented by Republican Joel Kitchens, since January 2015.

[4] The district was created in the 1972 redistricting act (1971 Wisc.

Act 304) which first established the numbered district system, replacing the previous system which allocated districts to specific counties.
