National Conference of State Legislatures: “This database contains state legislation related to redistricting. Bills found here deal with redistricting-related issues from 2018 onward. Bill information for the current year is updated each Tuesday. New measures are added as they are introduced or identified by NCSL staff. Bills may appear twice in carry-over states. In these states, please check the last date of action to ensure the status of the bill reflects the appropriate year. For databases covering election legislation, initiatives and referenda and term limits, visit NCSL’s Elections-Related Legislation Databases homepage.” [h/t Mary Whisner]
