District lines
U.S. Census Bureau 2024 cartographic boundary files (1:500,000): cb_2024_us_cd119_500k (Hawaii features only) for the 2 U.S. House districts, cb_2024_15_sldu_500k for the 25 state Senate districts, cb_2024_15_sldl_500k for the 51 state House districts, cb_2024_us_county_500k for counties and cb_2024_15_place_500k for city and town limits. These show the Hawaii's 2022 legislative maps drawn by the 2021 Reapportionment Commission _check. 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.
