Home to the Qualla Boundary, the eastern homeland of the Cherokee Nation, Jackson County blends rural Appalachian demographics with a significant Native American population — a combination that has historically kept its presidential margins closer than surrounding mountain counties.
The Democratic margin in Jackson County has rarely exceeded forty points in modern history; the Republican margin has rarely exceeded nineteen points. 2024 delivered the county to the Republican candidate by nine points.
Jackson County's demographics resemble the country more than they resemble most counties. A 79% non-Hispanic-white share, a 18% poverty rate, and a median household income of $55,815 — all within the broad national range. The county's voting pattern over the last decade is most similar to that of LaSalle County and Calhoun County.
