HistoryA character grade: shown, never part of Iroquois Township’s overall grade.
Founding eraNo founding year we can rely on, so the grade uses the other two–Homes built before 194044.4% of homes (±9.6) · typical IN town 14.4% · U.S. 8.4%A+National Register1 listing, 3 historic buildings, 26.5 per 10,000 residents · typical IN town 7.9 · U.S. 2.4B+

NewerOlder
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 Iroquois Township’s 26.5 sits above most of its state (69% of Indiana towns have fewer) while its 3 historic buildings outnumber those of 65% 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 (±9.6 points).
