Quantifying Gerrymandering in North Carolina

Understand

Using an ensemble of redistricting plans, we evaluate whether a given political districting faithfully represents the geo-political landscape.

• Redistricting plans are sampled by a Monte Carlo algorithm from a probability distribution that adheres to realistic and non-partisan criteria.
• Using the sampled redistricting plans and historical voting data, we produce an ensemble of elections that reveal geo-political structure within the state.
• We showcase our methods on the two most recent districtings of NC for the U.S.
