Fluvanna sits along the James River southeast of Charlottesville, and its 20,000 residents have trended steadily Republican in recent cycles after posting near-even splits in the mid-2000s, reflecting broader exurban realignment across Virginia's Piedmont.
The Democratic margin in Fluvanna County has rarely exceeded seventy-three points in modern history; the Republican margin has rarely exceeded thirty-seven points. 2024 delivered the county to the Republican candidate by six points.
Fluvanna County's demographics resemble the country more than they resemble most counties. A 76% non-Hispanic-white share, a 8% poverty rate, and a median household income of $96,768 — all within the broad national range. The county's voting pattern over the last decade is most similar to that of Spotsylvania County and Ada County.
