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 Otsego Township’s 0.0 sits below most of its state (32% of Michigan 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 C to B+. The pre-1940 share is a Census survey estimate (±5.1 points). Two sources give 1831.
