Redistricting Wraps Up

In this, the 200th anniversary year of the term "gerrymander," the process of designing new congressional districts is almost over. Of the 43 states with enough residents to have more than one House district, all but Kansas have adopted a final redistricting plan.

The dust still has to settle from legal challenges though — a dozen states still have pending litigation regarding their new congressional districts. And more than 40 states faced a legal challenge of some sort over new maps this cycle; many have since been dismissed.

One state legislator who can't seem to get enough of redistricting is Illinois State Rep. Mike Fortner, a physics professor and long-time redistricting hobbyist. He not only helped lead the process in his own state but also entered a "Draw the Line" competition in Ohio that was sponsored by citizen organizations. Fortner's map won the contest and was considered by the Ohio state legislature, though it was not ultimately adopted.

Five bills are pending in Congress to change the redistricting process to some extent, most calling for mandatory independent commissions, although none of the bills have been considered in committee.

The table above provides state-by-state information about the redistricting process, beginning with Louisiana and Arkansas, the first states to finalize their new maps. Click on the map icons to compare the new and old district lines for each state.

About the Data

Much of the data in the chart above is culled from the excellent site on redistricting kept up by Justin Levitt, an associate professor of law at Loyola Law School.

The Roll Call politics staff contributed the race ratings for 2012 as well as summaries of what happened in each state’s redistricting process, all of which appear when you click on the icon for an individual state. The district lines were rendered based on maps made available by the states.
