Picture of the districting plan
Author: Catherine Wang Xiang
Redistricting Principle(s) Prioritized: Good Government, Proportional Representation, and Hybrid (more than two of above)
Date: Apr 3, 2022
This map is a hybrid plan that includes principles of (1) good government, as it prioritizes keeping political subdivisions intact, and (2) partisan representation, with only a 0.6% efficiency gap. It prioritizes keeping counties intact and respecting precinct boundaries, except where it is necessary to comply with one-person, one-vote practices. This plan’s largest population deviation, for District 16, is 0.16%. At the same time, the map preserves the previous plan’s minority representation, with 2 majority Hispanic districts and 2 majority Black districts by voting age population. Based on the last previous presidential election, the state-wide Democratic vote share is 57.5%, the Republican is 40.6%. The map closely reflects this proportional representation, with a predicted 61% Democrat and 39% Republican seat share across scenarios. According to the PlanScore analysis, this proposed map has 9 Democratic seats, 6 Republican seats, and 2 competitive seats.
