District lines
U.S. Census Bureau 2024 cartographic boundary files (1:500,000): cb_2024_us_cd119_500k (Maine features only) for the 2 U.S. House districts, cb_2024_23_sldu_500k for the 35 state Senate districts, cb_2024_23_sldl_500k for the 151 state House districts, cb_2024_us_county_500k for counties and cb_2024_23_place_500k for city and town limits. These show the Maine's 2021 state Senate and House district maps (used 2022 through 2030). 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.
