What drives Mankato’s History grade
On its age, its old homes and the National Register, Mankato is more historic than 73% of U.S. towns, #41 of 273 in Minnesota. Its National Register listings hold the grade up; its age pulls it down.
B+
HistoryA character grade: shown, never part of Mankato’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 Mankato’s 60.5 sits above most of its state (95% of Minnesota towns have fewer) while its 275 historic buildings outnumber those of 95% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C+ to A. The pre-1940 share (±1.8 points) is firm at this size. Two sources give 1852.
