What drives Oconto’s History grade

On its age, its old homes and the National Register, Oconto is more historic than 81% of U.S. towns, #78 of 362 in Wisconsin. Its National Register listings hold the grade up; its age pulls it down.

HistoryA character grade: shown, never part of Oconto’s overall grade.

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 Oconto’s 75.7 sits above most of its state (92% of Wisconsin towns have fewer) while its 35 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 B to A. The pre-1940 share is a Census survey estimate (±4.8 points). The founding year is the first post office, not a stated founding date; Wikidata’s 1869 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. National Register: National Park Service, May 2026 list; each listing counted once (boundary changes and added documentation belong to their listing), and a historic district counts its contributing buildings.
