HistoryA character grade: shown, never part of Omro’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 Omro’s 4.5 sits above most of its state (65% of Wisconsin towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.
NoteThe founding year comes from Wikidata alone; no second source gives 1842.
