Redistricting analytics in Python

This repository (rdapy) re-implements the main analytics used in Dave's Redistricting, ignoring a few DRA-specific aspects (in particular, the five [0-100] ratings). Unlike the analytics used in the app (dra-analytics) which are implememented in TypeScript, these are implemented in Python.

Categories

The analytics are organized by area:

• Compactness: Various measures of compactness
• Equal: Population deviation
• Graph: Checks for contiguity & embeddedness
• Minority: Minority opportunity metrics
• Partisan: Various measures of partisan bias & responsiveness, as well as support for rank-vote graphs and seats-votes curves
• Splitting: County- & district-splitting and COI splitting

The samples directory contains some simple examples of how to exercies these functions and how to preprocess raw block-level data into the formats required by the analytics.
