DRA Analytics:

DRA examines how the map addresses 5 different criteria: Proportionality, Competitiveness, Minority Representation, Compactness, and Splitting. Its scores for each category are listed below on a 0-100 scale.  A higher number indicates a better score. Note that DRA’s Minority Representation analysis does not ensure Voting Rights Act (VRA) compliance. DRA also notes that some factors like communities of interest can be hard to quantify.

Below is a view of the House plan based on composite 2016-2020 election data which combines the results of several elections. The darker the shade of red or blue the safer the seat.  The lighter the shade, the less safe the seat is.

To rate the districts, DRA uses the Democratic vote share. The rank votes graph below illustrates the Democratic vote share in each district. Five of the districts had a Democratic vote share between 45% and 55%. This includes district 1, district 9, district 11, and district 13.

The declination (indicated by the white circle in the rank votes graph) of this congressional plan is lower than both those enacted by the North Carolina legislature.  The bigger the declination, the greater the partisan bias of the plan.

Out of the 4 districts with a democratic vote share between 45% and 55%,  2 lean Republican and 2 lean Democratic. According to the DRA analysis, the most likely outcome of this map would be a 7-7 split, 7 Democrats, 7 Republicans.
