Texas District 27
Score
Irregularity score 89 Very irregularLess compact than 93% of other congressional districts.
31st least compact of 429 nationally, 5th of 38 in Texas.
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
- 0.08at least as compact as 3% of districts on this measure
Area compared with perimeter. Low for jagged or snaking edges.
- Reock
- 0.38at least as compact as 22% of districts on this measure
Area compared with the smallest circle around the district, counting only land. Low for stretched shapes.
- Convex hull
- 0.57at least as compact as 8% 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
38% 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 (51.8%) belong to minority groups. The largest is Hispanic or Latino (40.5%). 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
