Advisory boundary-shape measurements
District compactness, without pretending it proves intent.
Compare Polsby–Popper and convex-hull ratios for official 2024 congressional and state legislative boundaries. Detailed measurements are checked against Census 1:500,000 geometry so resolution-sensitive shapes remain visible instead of becoming false precision.
Compactness is a descriptive screen, not a gerrymandering severity score.
Low values can reflect coastlines, islands, political subdivisions, communities of interest, legal requirements, or map resolution. They do not establish partisan intent, illegality, representational quality, fraud, or misconduct.

How the measures work
Two measures, one stability guard.
- Polsby–Popper
- 4π × area ÷ perimeter². A circle approaches 1. Coastline and boundary detail can sharply increase perimeter.
- Convex-hull ratio
- District area divided by its local equal-area convex hull. Disconnected or deeply concave shapes score lower.
- Resolution guard
- Detailed and 1:500,000 values are labeled stable only when their relative differences stay within 20% and 10%, respectively.
Election-result boundary
Outcome relationships are not calculated yet.
The repository does not yet contain a nationwide certified, same-plan-vintage district result set. Compactness is not joined to election outcomes across mismatched plans or geography.
That guard prevents district results from being compared against a different plan vintage or geography.
