Arizona District 9

69 Irregular

Less compact than 74% of other congressional districts.

113th least compact of 429 nationally, 3rd of 9 in Arizona.

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: 0.18at least as compact as 31% of districts on this measure
Area compared with perimeter. Low for jagged or snaking edges.
Reock: 0.44at least as compact as 36% of districts on this measure
Area compared with the smallest circle around the district, counting only land. Low for stretched shapes.
Convex hull: 0.69at least as compact as 26% 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

2024 presidential vote

Kamala Harris 34.3%, Donald Trump 65.7%

Shares of the votes for the two of them; other candidates are left out. Arizona used the same lines in 2024, so this is added up from precinct results. A precinct split between districts is divided by its House votes, so the figures are close estimates. Where the votes come from
