[4][5] Part of the Mille Lacs Indian Reservation is in Pine County.

[7] Pine County has been featured in a series of mysteries by Dean Hovey.

The county terrain consists of low rolling hills, carved with drainages, partly wooded and otherwise devoted to agriculture.

[10] The terrain slopes to the south and east, with its highest point near its northeast corner, at 1,319 ft (402 m) ASL.

25.10% of all households were made up of individuals, and 10.90% had someone living alone who was 65 years of age or older.

Between 1932 and 2008, Democrats won the county all but twice, with the two exceptions being nationwide Republican landslide victories in 1952 by Dwight D. Eisenhower and in 1972 by Richard Nixon (by only 87 votes).

The Democratic streak finally broke in 2012, when Republican challenger Mitt Romney barely won the county over incumbent Democrat Barack Obama by less than 1% and a margin of just 95 votes, becoming the first Republican to win the county in 40 years.

The 2016 election saw a dramatic rightward turn, as Donald Trump won the county by a margin of over 26%, and he further increased his margin of victory to over 30% in 2020 and over 35% in 2024, as Trump became the first Republican to win over 60% of the vote in Pine County since Warren G. Harding a century earlier.

This trend also continued in 2022, with Pine County voting Republican for all statewide races and the concurrent US House race, solidifying the counties realignment to Republicans.
