More historic than 40% of U.S. towns, on its age, its old homes and the National Register.
On its age, its old homes and the National Register, Armstrong Township is more historic than 40% of U.S. towns. Its share of homes from before 1940 holds the grade up; its National Register listings pull it down.
Indiana towns list more on the Register than most of the country (a typical Indiana town has 7.9 per 10,000 residents, the U.S. 2.4), so Armstrong Township’s 0.0 sits below most of its state (22% of Indiana 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.

Armstrong Township is more historic than 40% of U.S. towns. The History grade combines the town’s founding era, the share of homes built before 1940 and its National Register listings. It’s a character grade, so it isn’t part of the overall grade. How it works.
21% of Armstrong Township’s homes were built before 1940 (Census estimate, ±7.0 points), against a typical 14% for an Indiana town; the median home was built in 1971.
