What drives Monticello’s History grade

On its age, its old homes and the National Register, Monticello is more historic than 92% of U.S. towns. All 3 inputs are above most U.S. towns; its share of homes from before 1940 ranks highest and its National Register listings lowest.

Wisconsin towns list more on the Register than most of the country (a typical Wisconsin town has 3.0 per 10,000 residents, the U.S. 2.4), so Monticello’s 16.8 sits above most of its state (81% of Wisconsin towns have fewer) while its 2 historic buildings outnumber those of 60% 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 (±8.5 points). The founding year is the first post office, not a stated founding date.
