Redistricting FAQ

1. What is redistricting?

Redistricting is the process of redrawing legislative or congressional district boundaries.

2. How often does redistricting occur?

At least once every ten years following a United States census. Redistricting may occur more than once in a ten-year period if ordered by a court.

3. Why is redistricting done?

Redistricting is required by both the federal and state constitutions to ensure that political representation is proportional. Under constitutional law, each United States representative should represent approximately the same number of people as other United States representatives in that state, and each state legislator should represent approximately the same number of people as other state legislators. Therefore, the districts they are elected from must be roughly equal in population, though some population variance is permissible to satisfy other redistricting criteria.

4. Who conducts redistricting in Idaho?

The Idaho Commission for Reapportionment (also known as the Redistricting Commission). The Commission is bipartisan and composed of six appointed members. You may review biographies of the Commissioners here .

7. How long will redistricting take?

From the day of its first meeting, the Commission will have up to 90 days to adopt congressional and legislative redistricting plans.

8. Are there criteria, besides population, that determine how district boundaries will be drawn?

Yes. Under Idaho law, redistricting plans are governed by the following criteria:

  1. Districts shall be substantially equal in population and should comply with all applicable federal standards and statutes;

  2. Population as determined by the U.S. Census Bureau shall be exclusive permissible data;

  3. Division of counties shall be avoided whenever possible. If a county must be divided, then the number of such divisions, per county, should be kept to a minimum. Districts containing more than one county shall be composed of contiguous counties. Counties shall not be divided to protect a particular political party or political incumbent;

  4. If a legislative district contains more than one county or a portion of a county, then the counties or the portion must be connected by highways (this requirement may be set aside by Commission vote under certain circumstances);

  5. To the maximum extent possible, districts shall preserve traditional neighborhoods and local communities of interest;

  6. To the maximum extent possible, redistricting plans should avoid drawing districts that are oddly shaped; and

  7. District boundaries shall retain local voting precinct boundary lines (this requirement may be set aside by Commission vote under certain circumstances).
