Redistricting is the process of redrawing the lines that define political districts. For state and federal districts, this typically occurs after the completion of the federal census every ten years. Most of the rules governing how the lines are drawn are up to each individual state. As a result, there are many different models across the country for redrawing the lines. To understand Oregon’s unique process, see “How it works in Oregon.”

Geographically-based representation, means that districts must be redrawn from time to time as┬ácommunities change and people move around. To underscore its importance, the first Article of the US Constitution specifies how representation is to be divided amongst the states. For a brief history of redistricting (and Gerrymandering), see our “History” page.

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.”
