District lines
U.S. Census Bureau 2024 cartographic boundary files (1:500,000): cb_2024_us_cd119_500k (Kansas features only) for the 4 U.S. House districts, cb_2024_20_sldu_500k for the 40 state Senate districts, cb_2024_20_sldl_500k for the 125 state House districts, cb_2024_us_county_500k for counties and cb_2024_20_place_500k for city and town limits. These show the 2022 Kansas legislative maps in use for 2022-2030 (House: Freestate 3F plan; Senate: Liberty 3 plan; State Board of Education: Apple 7 plan). 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.
