What drives Waterloo Township’s History grade
On its age, its old homes and the National Register, Waterloo Township is more historic than 75% of U.S. towns, #166 of 701 in Michigan. All 3 inputs are above most U.S. towns; its age ranks highest and its share of homes from before 1940 lowest.
B+
HistoryA character grade: shown, never part of Waterloo 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 Waterloo Township’s 3.4 sits above most of its state (73% 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 A−. The pre-1940 share is a Census survey estimate (±4.3 points). The founding year is the first post office, not a stated founding date.
Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24.
