Polarization is a measure of how likely the districts in a plan will stay with their parties. A low polarization score indicates that the districts in a plan are more responsive to changes in the electoral mood and reflects the overall competitiveness of the districts.
The polarization score is based on the PVI of the districts in a plan:
For each highly competitive district (PVI 0 or 1) add 0
For each competitive district (PVI 2 through 5) add +1
For each noncompetitive district (PVI 6 or greater) add +2
The total is the POLARIZATION score for the plan.
