HistoryA character grade: shown, never part of Mount Carmel’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 Mount Carmel’s 5.8 sits above most of its state (77% of Illinois towns have fewer) while its 4 historic buildings outnumber those of 68% 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 (±6.0 points). Two sources give 1815.

On June 4, 1877, a tornado of F4 intensity touched down just west of Mount Carmel and moved east-northeast, devastating the town. The storm's line of destruction wreaked havoc on a large part of the territory between Third and Fifth streets. As described in a local newspaper at the time:"During its prevalence the air was filled with flying roofs, windows, doors, lumber, rails, clothing, etc. Much of the debris was carried more than a mile away. Thirteen persons were killed outright, and many others will undoubtedly die of their injuries. There are also several others reported missing who are probably buried in the ruins. It being a rainy day, many farmers who could not work at home were in town. The county court was also in session, which caused many people to be in the city.
