District lines
U.S. Census Bureau 2024 cartographic boundary files (1:500,000): cb_2024_us_cd119_500k (Mississippi features only) for the 4 U.S. House districts, cb_2024_28_sldu_500k for the 52 state Senate districts, cb_2024_28_sldl_500k for the 122 state House districts, cb_2024_us_county_500k for counties and cb_2024_28_place_500k for city and town limits. These show the {'url': 'https://www.sos.ms.gov/elections-voting', 'label': 'Mississippi Secretary of State', '_check': 'No legislative regular races in 2026. Specials for House 70/77 use the 2022 lines per SOS directive (Mississippi Today, Oct 6 2026); official map file URL not found'}. 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.
