History grade
What drives Wilmette’s History grade
On its age, its old homes and the National Register, Wilmette is more historic than 85% of U.S. towns, #124 of 768 in Illinois. Its National Register listings hold the grade up; its age pulls it down.
A
HistoryA character grade: shown, never part of Wilmette’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 Wilmette’s 352 sits above most of its state (98% of Illinois towns have fewer) while its 969 historic buildings outnumber those of 99% 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 (±2.7 points) is firm at this size. The founding year is the first post office, not a stated founding date; Wikidata’s 1872 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.

What stands out about Wilmette’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Wilmette was a forested area with high bluffs along its lakeshore. Before European settlement, members of the Potawatomi tribe lived in the area that would later become Wilmette. Native Americans were forced out of the area by treaties in the 1820s and 1830s.
The village is named in honor of Archange and Antoine Ouilmette.
