2020 Redistricting - Past Plans

The Redistricting Report Card uses a powerful and unique set of analytics to grade each state’s newly-drawn maps during the redistricting process. The Redistricting Report Card that converts metrics of partisan and racial performance data to a grade, using quantitative rubrics that are the same from state to state. These metrics use our own statistical analysis standards, computational simulations, and data from the U.S. Census and VEST. We gratefully acknowledge the efforts of the Voting and Election Science Team (VEST) in gathering precinct-level data of election results across the nation.
