B+
HistoryA character grade: shown, never part of Eaton’s overall grade.
Indiana towns list more on the Register than most of the country (a typical Indiana town has 7.9 per 10,000 residents, the U.S. 2.4), so Eaton’s 6.1 sits near the middle of its state (57% of Indiana 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 C+ to A−. The pre-1940 share is a Census survey estimate (±7.6 points). Two sources give 1854.
