HistoryA character grade: shown, never part of Brillion’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 Brillion’s 3.0 sits near the middle of its state (62% of Wisconsin towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.
