Few Michigan towns list much on the Register (a typical Michigan town has 0.0 per 10,000 residents, the U.S. 2.4), so Cooper Township’s 1.0 sits above most of its state (66% of Michigan towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from B to B+. The pre-1940 share is a Census survey estimate (±5.1 points). The founding year is the first post office, not a stated founding date.
