Key Metrics

  • Efficiency Gap: Measures wasted votes asymmetry
  • Mean-Median: Party vote vs seat share difference
  • Compactness: How circular/regular districts are

An efficiency gap > 8% suggests possible gerrymandering.

Gerrymandering Techniques

Packing: Concentrate opponent voters into few districts (waste by excess)

Cracking: Split opponent voters across districts (waste by defeat)
