On its age, its old homes and the National Register, Rapidan Township is more historic than 46% of U.S. towns. Its share of homes from before 1940 holds the grade up; its National Register listings pull it down.
Minnesota towns list about as much on the Register as the country (a typical Minnesota town has 2.1 per 10,000 residents, the U.S. 2.4), so Rapidan Township’s 0.0 sits below most of its state (23% of Minnesota towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24.
