HistoryA character grade: shown, never part of Trout Lake Township’s overall grade.
Minnesota towns list about as much on the Register as the country (a typical Minnesota town has 2.1 per 10,000 residents, the U.S. 2.4), so Trout Lake Township’s 53.3 sits above most of its state (94% of Minnesota towns have fewer) while its 6 historic buildings outnumber those of 72% 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 (±3.9 points).
