Wisconsin District 1

36 Compact

Less compact than 31% of other congressional districts.

296th least compact of 429 nationally, 5th of 8 in Wisconsin.

A score describes shape, not intent. Coastlines, rivers and the Voting Rights Act can all make a district irregular. How scores work

The three measures

Polsby-Popper: 0.28at least as compact as 59% of districts on this measure
Area compared with perimeter. Low for jagged or snaking edges.
Reock: 0.55at least as compact as 67% of districts on this measure
Area compared with the smallest circle around the district, counting only land. Low for stretched shapes.
Convex hull: 0.83at least as compact as 67% of districts on this measure
Area compared with a rubber band stretched around the district, counting only land. Low for bites and tentacles.

Each measure runs from 0 to 1, where 1 is a perfect circle or a shape with no dents.

The state's edge

39% of this district's border is the state's edge: a coastline, a national border or a state line. Mapmakers don't choose those lines. A ragged one, like a coastline or a river, lowers Polsby-Popper. Reock and convex hull count only the state's own land, so water and neighboring states don't count against them. More on the state's edge
