Less compact than 50% of other congressional districts.
217th least compact of 429 nationally, 44th of 52 in California.
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
0.31at least as compact as 72% of districts on this measure
Area compared with perimeter. Low for jagged or snaking edges.
Reock
0.16among the least compact 1% of districts on this measure
Area compared with the smallest circle around the district, counting only land. Low for stretched shapes.
Convex hull
0.88at least as compact as 84% 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
78% 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
Who lives here
Most of this district's voting-age residents (55.4%) belong to minority groups. The largest are Asian (33.7%) and Hispanic or Latino (13.2%). The Voting Rights Act can require districts that keep a minority community together so it can elect candidates it prefers, and those districts can be irregular on purpose. A district like this isn't necessarily drawn for that reason, and the site doesn't know whether this one was. Figures are from the 2020 Census. How these are counted
