What drives McLeansboro Township’s History grade

On its age, its old homes and the National Register, McLeansboro Township is more historic than 85% of U.S. towns, #135 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.

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 McLeansboro Township’s 11.0 sits above most of its state (84% of Illinois towns have fewer) while its 4 listings outnumber those of 68% of U.S. towns.

How sure. Graded on any two of the three inputs instead, the letter would still be A−. The pre-1940 share is a Census survey estimate (±6.6 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.
