HistoryA character grade: shown, never part of Pierson Township’s overall grade.
Founding eraNo founding year we can rely on, so the grade uses the other two–Homes built before 194040.7% of homes (±32.4) · typical IN town 14.4% · U.S. 8.4%ANational Register1 listing, 5.8 per 10,000 residents · typical IN town 7.9 · U.S. 2.4B−
All U.S. towns we grade (21,289)Ahead of 86%
NewerOlder
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 Pierson Township’s 5.8 sits near the middle of its state (56% of Indiana towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.
How sure. Graded on two of the three inputs, so a change in either one moves the letter more than it would with three. The pre-1940 share is a Census survey estimate (±32.4 points).
