HistoryA character grade: shown, never part of Hadley Township’s overall grade.
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 Hadley Township’s 2.2 sits above most of its state (69% 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 still be B+. The pre-1940 share is a Census survey estimate (±6.2 points). Two sources give 1836.
