What drives Channahon’s History grade

On its age, its old homes and the National Register, Channahon is more historic than 59% of U.S. towns, #338 of 768 in Illinois. Its National Register listings hold the grade up; its share of homes from before 1940 pulls it down.

B
HistoryA character grade: shown, never part of Channahon’s overall grade.
All U.S. towns we grade (21,289)Ahead of 59%

Illinois towns of 2,500+ (768)Ahead of 56%

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 Channahon’s 6.5 sits above most of its state (78% of Illinois towns have fewer) while its 9 historic buildings outnumber those of 75% of U.S. towns.

How sure. Graded on any two of the three inputs instead, the letter would range from C+ to A−. The pre-1940 share (±0.9 points) is firm at this size. The founding year is the first post office, not a stated founding date; Wikidata gives 1961.

Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24.

The story

How Channahon came to be

From Wikipedia’s history of Channahon.

Read it all →

Archaeological evidence suggests that the land on which the village now stands was inhabited as long as three to four thousand years ago by Mound Builders. When white settlers arrived in the early 1830s, the region was populated by Potawatomi, with whom the early settlers had friendly relations. The settlers began to call the area "Channahon," a Potawatomi phrase translated as "meeting of the waters."

The sandstone quarries of Channahon furnish a very superior quality of building-stone, and were opened originally by Joseph Lewis, long one of the prominent business men of the village of Channahon. Another quarry of a similar character was opened and worked for a time by Patrick Conroy. None of these quarries are now in operation, a fact that seems strange, when we consider the excellent and cheap transportation of freights by way of the Illinois & Michigan Canal. With the apparently inexhaustible supply, the ease with which the stone is reached, it would be natural to suppose that this would be
