History grade
What drives Bloomington’s History grade
On its age, its old homes and the National Register, Bloomington is more historic than 89% of U.S. towns, #88 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 Bloomington’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 Bloomington’s 50.6 sits above most of its state (91% of Illinois towns have fewer) while its 399 historic buildings outnumber those of 96% 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 (±1.3 points) is firm at this size. The founding year is the first post office, not a stated founding date; Wikidata gives 1857.
Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24.
