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 Middleport Township’s 98.8 sits above most of its state (93% of Illinois towns have fewer) while its 36 historic buildings outnumber those of 83% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from A− to 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.
