Campaign Legal Center (CLC) has launched a new feature on PlanScore.org with a library. Visitors have access to analyses of noteworthy redistricting maps proposed around the country scored using various fairness metrics, as well as links to raw files and authoritative sources. PlanScore.org is an empowerment tool to measure voting maps and evaluate them for partisan skew.  

During the 2021 redistricting cycle, PlanScore.org has been collecting and analyzing new district plans as they are proposed in states nationwide. It is intended to be used by map drawers to help them in ensuring they are creating fair maps, and for policymakers, advocates and journalists to hold map drawers accountable to fair districting standards.  

The site’s library feature contextualizes the gerrymandering taking place this cycle by enabling visitors to click on states and compare them to other states or previous maps from the same state. PlanScore.org presents the most comprehensive historical dataset of partisan gerrymandering ever assembled, going back to the 1970s. 

Both the historical and present-day maps on PlanScore.org include all four main academic measures of gerrymandering — efficiency gappartisan biasmean-median difference and declination

This gives people multiple ways to determine whether the maps being proposed this year would create competitive districts that accurately and equitably represent the communities that they encompass.  

The voting districts that will be finalized in the coming months will be cemented for the next 10 years. During that time, they will shape our communities and our lives.

We need fair maps because they will ensure that our communities have equal access to resources like schools and hospitals, and that voters can pick our leaders, instead of having our leaders pick their voters.  

PlanScore.org empowers voters to hold map drawers accountable and demand fair maps during this critical map drawing year. By using this site, advocates can measure partisan gerrymandering directly and map drawers can ensure that they draw fair maps.
