District lines

U.S. Census Bureau 2024 cartographic boundary files (1:500,000): cb_2024_us_cd119_500k (Oregon features only) for the 6 U.S. House districts, cb_2024_41_sldu_500k for the 30 state Senate districts, cb_2024_41_sldl_500k for the 60 state House districts, cb_2024_us_county_500k for counties and cb_2024_41_place_500k for city and town limits. These show the {'url': 'https://www.oregonlegislature.gov/FindYourLegislator/leg-districts.html', 'label': 'Oregon Legislature: find your district', '_check': 'URL not opened this session'}. District files are converted without simplification; county outlines and city limits are simplified for display. Near a boundary line they can be off by a block or more.
