What drives Clinton Township’s History grade

On its age, its old homes and the National Register, Clinton Township is more historic than 94% of U.S. towns, #98 of 593 in Indiana. All 3 inputs are above most U.S. towns; its share of homes from before 1940 ranks highest and its age lowest.

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 Clinton Township’s 52.8 sits above most of its state (75% of Indiana towns have fewer) while its 47 historic buildings outnumber those of 84% of U.S. towns.

How sure. Graded on any two of the three inputs instead, the letter would range from A− to A. The pre-1940 share is a Census survey estimate (±5.3 points). The founding year is the first post office, not a stated founding date; Wikidata’s 1829 falls in the same era, so the grade doesn’t depend on which one is used.

Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24. National Register: National Park Service, May 2026 list; each listing counted once (boundary changes and added documentation belong to their listing), and a historic district counts its contributing buildings.

The story

How Clinton Township came to be

From Wikipedia’s history of Clinton Township.

Read it all →

The city was established in 1829 and is named for DeWitt Clinton, governor of New York from 1817 to 1823. Many of Clinton's original settlers were immigrants working in coal mines, many from Italy. According to Vermillion County naturalization records, "...from 1856 to 1952... Vermillion County received almost 3,550 new citizens of foreign birth, the largest number coming during the first twelve years of [the 20th] century. Italians accounted for one-third, or 1,178, of the total number who filed Declarations, with Austrians the next largest group (675) and then Scots. At least 77 percent of the Italians were from the northern regions of Italy." This was in contrast to the majority of Italian immigrants to America during this same time period that hailed from southern Italy. Over time, the coal mining industry in Clinton ended but many of the Italian settlers stayed at Clinton.
