What drives Manhattan’s History grade
On its age, its old homes and the National Register, Manhattan is more historic than 38% of U.S. towns. Its share of homes from before 1940 holds the grade up; its National Register listings pull it down.
C+
HistoryA character grade: shown, never part of Manhattan’s overall grade.
Montana towns list more on the Register than most of the country (a typical Montana town has 12.7 per 10,000 residents, the U.S. 2.4), so Manhattan’s 0.0 sits below most of its state (16% of Montana towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from D to B−. The pre-1940 share is a Census survey estimate (±12.4 points). The founding year is the first post office, not a stated founding date.
