HistoryA character grade: shown, never part of Henry Township’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 Henry Township’s 310 sits above most of its state (92% of Indiana towns have fewer) while its 94 historic buildings outnumber those of 89% of U.S. towns.
How sure. Graded on two of the three inputs, so a change in either one moves the letter more than it would with three. The pre-1940 share is a Census survey estimate (±6.8 points).
