A
HistoryA character grade: shown, never part of Indian Grove Township’s overall grade.
Few Illinois towns list much on the Register (a typical Illinois town has 0.5 per 10,000 residents, the U.S. 2.4), so Indian Grove Township’s 4.9 sits above most of its state (75% of Illinois towns have fewer) while its 2 listings outnumber those of 60% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would still be A−. The pre-1940 share is a Census survey estimate (±6.4 points). The founding year is the first post office, not a stated founding date.
