On its age, its old homes and the National Register, Linn is more historic than 88% of U.S. towns, #45 of 362 in Wisconsin. All 2 inputs are above most U.S. towns; its National Register listings ranks highest and its share of homes from before 1940 lowest.

HistoryA character grade: shown, never part of Linn’s overall grade.
Wisconsin towns list more on the Register than most of the country (a typical Wisconsin town has 3.0 per 10,000 residents, the U.S. 2.4), so Linn’s 18.5 sits above most of its state (82% of Wisconsin towns have fewer) while its 5 historic buildings outnumber those of 70% of U.S. towns.
How sure. Graded on two of the three inputs, so a change in either one moves the letter more than it would with three. The pre-1940 share is a Census survey estimate (±4.4 points).
