Public Mapping Project
The drawing of electoral districts is among the least transparent
processes in democratic governance. All too often, redistricting
authorities maintain their power by obstructing public participation.
The resulting districts embody the goals of politicians to the
detriment of the representational interests of communities and the
public at large.
We seek to change this power balance by making it
possible for the public to draw the boundaries of their communities and
to generate redistricting plans for their state and localities --
through their web-browsers. The Public Mapping Project is developing District Builder, an open
source software redistricting application designed to give the public transparent,
accessible, and easy-to-use on-line mapping tools.
This technological innovation will enable greater
public participation where redistricting authorities solicit public
input. Where redistricting authorities are not responsive to the
representational needs of the public, plans drawn by the public may be
used as a yardstick by which to compare a redistricting authority’s
plan against. And where the courts must step in when the regular
redistricting process breaks down, judges will have a greater menu of
options to consider.
Learn More About Our Vision
Drs. Altman and McDonald describe where this project fits in the history of redistricting technology in this Duke Journal of Constitutional Law and Public Policy article. Also read a Washington Post opinion editorial calling for greater transparency and public participation in redistricting, based on principles articulated by the Public Mapping Project advisory board. Dr. McDonald has presented these ideas to the National Conference of State Legislatures and the Oregon State Legislature. |

Draw the Lines PAWe are proud to support Draw the Lines PA in providing data and software for their redistricting competitions. Anyone is allowed to use our DistrictBuilder software to draw maps for their competitions, so check them out! Data! Data! Data!In preparation for the 2021 redistricting, we are collecting precinct boundaries nationwide and merging these boundaries with statewide election results. We have collected boundary data from nearly every locality in the country and are in process of adding election results. The states that we have released complete 2016 data are available here.

A Citizens Guide to Redistricting
The Brennan Center for Justice at New York University School of Law's comprehensive Citizen's Guide to Redistricting explains the various processes and criteria that govern redistricting across the fifty states.
The Voting Rights Act
The Voting Rights Act is an important federal redistricting requirement that ensures our representatives reflect America's racial and ethnic diversity. It enjoys overwhelming bipartisan congressional support. The U.S. Department of Justice and the NAACP Legal Defense Fund's Redrawing the Lines are excellent sources of information about the Voting Rights Act.
The Redistricting Game
The University of Southern California's Game Innovation Lab has created this fun and informative redistricting simulation which teaches how redistricting works.
Gerrymandering: The Documentary
The Gerrymandering documentary lays out the pathologies of partisan gerrymandering whereby districts are drawn to favor politicians, not the public. | |
