Redistricting is the process of redrawing the lines that define political districts. For legislative and congressional districts, this typically occurs after the completion of the federal census every ten years.

Geographically-based representation, means that districts must be redrawn from time to time as communities change and voters move to different areas of the state.

The 2011 redistricting was the first time since 1911 that the Legislature successfully passed a redistricting plan that was not later modified by the courts. To learn about some of the more recent redistricting iterations in Oregon, visit Recent Oregon History. Nearly every time redistricting comes up, there are groups and individuals who have ideas to improve the process. We have collected a few of those ideas under “History of reform in Oregon.”

For the truly inspired redistricting-fan, we have also listed some of the best national websites that look at aspects of redistricting, including redistricting games, music videos and more. Check our our “Resources” page to bring your expertise to the next level.
