Home to Naval Weapons Station Yorktown and straddling the York River, this small Tidewater county leans modestly Republican but has trended competitive as Hampton Roads suburbs grow more diverse and transient.
The shift began with civil rights. 1968 marked the realignment in York County, by a eleven points margin. The Republican margin reached its widest at fifty-four points in 1928. The 2024 margin was six points.
The political shift has tracked, in York County, the political shift of the South more broadly. A 68% non-Hispanic-white share, a median household income of $109,956, and a 6% poverty rate describe the demographic context. The county's voting pattern over the last decade is most similar to that of Delaware County and Fayette County.
