History
The district was created in the 1972 redistricting act which first established the numbered district system, replacing the previous system which allocated districts to specific counties. The 42nd district was drawn roughly in line with the boundaries of the previous Outagamie County 1st district.The 42nd district boundaries have shifted significantly over the various redistrictings of the state, but the location of the district has remained consistent in south-central Wisconsin since the 1983 redistricting.
