HistoryA character grade: shown, never part of Shiloh Valley 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 Shiloh Valley Township’s 77.8 sits above most of its state (93% of Illinois towns have fewer) while its 100 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 (±1.5 points) is firm at this size.
