On its age, its old homes and the National Register, Union Township is more historic than 58% of U.S. towns, #335 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 Union Township’s 45.7 sits above most of its state (74% of Indiana towns have fewer) while its 41 historic buildings outnumber those of 84% of U.S. towns.
