Building Non-Partisan Political Power
A Tool to Add Political Jurisdictions to Membership Lists
This online tool is intended for use by institutions affiliated with the Industrial Areas Foundation organizations in the Northwest (see list above) and requires a password.  The tool allows institutions to add information to their membership list that will tell them each member’s:
  • Legislative District
  • School District
  • Congressional District
  • County or County Council District
  • City
  • Precinct (selected counties)
Please note that matching rates depend on data quality and usually range from 65-90%.  The tool uses a member’s address to determine their precise geographical location (geocoding) and therefore requires accurate street addresses (P.O. Boxes, incomplete addresses, and locations outside of Washington and Oregon will fail).  Since the tool uses mapping technology rather than voter lists (allowing it to return data for unregistered voters as well as those who are registered), some errors may occur if an individual lives near a boundary line.  If there is a question, please visit the legislative district finder tool at:
