District lines
U.S. Census Bureau 2024 cartographic boundary files (1:500,000): cb_2024_us_cd119_500k (New Jersey features only) for the 12 U.S. House districts, cb_2024_34_sldu_500k for the 40 state Senate districts, cb_2024_34_sldl_500k for the 40 state House districts, cb_2024_us_county_500k for counties and cb_2024_34_place_500k for city and town limits. These show the New Jersey Apportionment Commission's 2021 legislative map (40 districts; each elects 1 senator and 2 Assembly members). Not used this year: the legislature is not on the 2026 ballot.. 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.
