On its age, its old homes and the National Register, Ohio Township is more historic than 50% of U.S. towns, #383 of 593 in Indiana. Its National Register listings hold the grade up; its share of homes from before 1940 pulls 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 Ohio Township’s 6.9 sits near the middle of its state (58% of Indiana towns have fewer) while its 29 historic buildings outnumber those of 81% of U.S. towns.
