Niagara County, anchored by Lockport and the falls-adjacent city of Niagara Falls, shifted from a competitive swing county to a reliably Republican-leaning one as its industrial-era Democratic base eroded alongside manufacturing employment.
Across the recorded series it reached a Democratic high of 40.2 points in 1964 and a Republican high of 47.0 points in 1924. Between 2020 and 2024 the county moved 5.2 points toward the Republican candidate; the 2024 margin was 14.9 points.
A population of 210,721, a 82% non-Hispanic-white share, and a median household income of $69,633 describe the county. The county's voting pattern over the last decade is most similar to that of Luzerne County and Alpena County.
