Each Senate district is numbered by sequential House districts (Senate 1 consists of House 1 & 2).Verify district accuracy by checking with the Oregon Secretary of State's Office or Oregon Department of Administrative Services - Geospatial Enterprise Office before conducting any legally binding analysis.
