Partisan Dislocation

Partisan Dislocation

This package implements the partisan dislocation measure from Deford, Eubank, Rodden.

It takes as input a GeoDataframe of polygons with columns containing vote counts for both political parties for each polygon. it includes three functions which, when used sequentially, will return a GeoDataframe of representative voter point along with associated dislocation scores for each point.

In addition, this repository also include the shapefiles of US precincts and their vote totals from the 2008 presidential election used in Deford, Eubank, Rodden. these can be found in the folder "2008_presidential_precinct_data." Note that to download this data, you will have to first install git-lfs.

The three functions provided by the package are:

• random_points_in_polygon: takes a polygon GeoDataframe with the number of votes cast democrats and republicans in each polygon and returns a GeoDataframe off of representative voter points.
• calculate_voter_knn: takes a voter point GeoDataframe and returns a voter point GeoDataframe with voter knn scores.
• calculate_dislocation: takes a voter point GeoDataframe with knn scores and a GeoDataframe with electoral district polygons and returns voter dislocation scores.

Demonstration of how the package can be used can be found in dislocation_tutorial.ipynb.
