HistoryA character grade: shown, never part of Centralia’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 Centralia’s 48.1 sits above most of its state (90% of Illinois towns have fewer) while its 57 historic buildings outnumber those of 86% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from B− to A. The pre-1940 share is a Census survey estimate (±3.0 points). Two sources give 1853.
