Top 100 counties

Counties ≥ 5,000 population, ranked by Median income. “2024” is the two-party presidential margin; “Since ’20” is the 2020→2024 shift in points (positive = toward Democrats). Sources: U.S. Census ACS 2024 5-year · 2020 U.S. Religion Census (ASARB) · MIT Election Lab.

Rankings suppress places below 5,000 population, where small-sample ACS shares get noisy. Demographic shares are American Community Survey 5-year estimates (ancestry table B04006, language C16001) and the 2020 U.S. Religion Census; every figure traces to a named federal or academic source. The vote columns are presidential — a place can be demographically homogeneous and politically split, which is exactly what these tables are built to show.
