2015 Redistricting Legislation


definition of legislationDuring the 2015 legislative session, 152 bills regarding redistricting laws were considered in 34 states and Puerto Rico. Thirty-eight of these bills from 16 states related to constitutional amendments. These addressed topics such as commissions, public input, criteria for redistricting, prisoner allocation and other topics.

The most common topic for legislation in 2015 dealt with the redistricting process. There were 104 bills dealing with redistricting commissions or the process of drawing the district lines by state legislatures. Of those, 86 dealt with the establishment of a commission, a change in the commission makeup, or the criteria to be used by the commission. The remaining 16 bills addressed criteria for redistricting by the legislature, or redrew district lines. Of note, Indiana established a study committee to review its redistricting process.

Two bills addressed how the public could provide input during the redistricting process. (See Oregon’s enacted legislation below.) Fifteen bills addressed prisoner allocation, either relating to data collection or residency classification for purposes of drawing district lines.

 Three bills addressed the courts, including the Texas enacted bill (see below) and a Pennsylvania bill giving specified courts the power to draw district lines. Further, 20 bills sought to make technical adjustments to district lines, or to the redistricting process.
