Trade-Offs in Fair Redistricting
Maps and Code
In the paper, we explore empirically the ‘price’ one must pay in terms of the compactness of districts in order to improve the partisan symmetry of a plan (and vice versa) in North Carolina and Pennsylvania. Due to space constraints, we could not include all of the Pareto-optimal plans in the paper itself, so we include them here. There are 13 plans for North Carolina and 25 for Pennsylvania, including the four displayed in the paper. Click a state below to see the plans for that state.
