New District & Precinct Boundaries

Every ten years following the national census, the Idaho Commission on Reapportionment establishes new Congressional and Legislative district boundaries. Based on those districts, the County defines voting precincts within the county. Precincts are used to determine where residents vote and how many residents vote in the same location. See the new precinct boundaries.
