Below: maps from 1951 on.
More historic than 58% of U.S. towns, on its age, its old homes and the National Register.
On its age, its old homes and the National Register, Etna-Troy Township is more historic than 58% 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 Etna-Troy 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.
