HistoryA character grade: shown, never part of Hinsdale’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 Hinsdale’s 175 sits above most of its state (96% of Illinois towns have fewer) while its 300 historic buildings outnumber those of 95% 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 (±2.5 points) is firm at this size. The founding year is the first post office, not a stated founding date; Wikidata’s 1873 falls in the same era, so the grade doesn’t depend on which one is used.
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.
