Oxford County's economy centers on timber, agriculture, and small manufacturing, and its largely white, non-college electorate has shifted more than 20 points toward Republican presidential candidates over the past four election cycles.
The Democratic margin in Oxford County has rarely exceeded forty-four points in modern history; the Republican margin has rarely exceeded forty-six points. 2024 delivered the county to the Republican candidate by thirteen points.
Oxford County's demographics resemble the country more than they resemble most counties. A 93% non-Hispanic-white share, a 14% poverty rate, and a median household income of $60,173 — all within the broad national range. The county's voting pattern over the last decade is most similar to that of St. Lawrence County and Franklin County.
