A
HistoryA character grade: shown, never part of Pittsfield’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 Pittsfield’s 778 sits above most of its state (99% of Illinois towns have fewer) while its 344 historic buildings outnumber those of 96% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from A− to A+. The pre-1940 share is a Census survey estimate (±7.0 points). The founding year is the first post office, not a stated founding date.
