What drives Lebanon’s History grade
On its age, its old homes and the National Register, Lebanon is more historic than 88% of U.S. towns, #97 of 768 in Illinois. All 3 inputs are above most U.S. towns; its National Register listings ranks highest and its share of homes from before 1940 lowest.
A
HistoryA character grade: shown, never part of Lebanon’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 Lebanon’s 326 sits above most of its state (98% of Illinois towns have fewer) while its 146 historic buildings outnumber those of 91% 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 (±5.6 points). The founding year is the first post office, not a stated founding date.
Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24. National Register: National Park Service, May 2026 list; each listing counted once (boundary changes and added documentation belong to their listing), and a historic district counts its contributing buildings.
