HistoryA character grade: shown, never part of Clintonia 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 Clintonia Township’s 2.8 sits above most of its state (69% of Illinois towns have fewer) while its 2 listings outnumber those of 60% 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 (±5.3 points).
