What drives Plainfield’s History grade
On its age, its old homes and the National Register, Plainfield is more historic than 68% of U.S. towns, #302 of 593 in Indiana. Its National Register listings hold the grade up; its share of homes from before 1940 pulls it down.
B+
HistoryA character grade: shown, never part of Plainfield’s overall grade.
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 Plainfield’s 49.2 sits above most of its state (75% of Indiana towns have fewer) while its 179 historic buildings outnumber those of 93% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C+ to A. The pre-1940 share (±0.8 points) is firm at this size. The founding year is the first post office, not a stated founding date; Wikidata’s 1839 falls in the same era, so the grade doesn’t depend on which one is used.

What stands out about Plainfield’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
In 1822, a tract of land which included the area now known as Plainfield was obtained by Jeremiah Hadley of Preble County, Ohio. Ten years later he sold it to his son, Elias Hadley. Levi Jessup and Elias Hadley laid out the town in 1839. Plainfield was incorporated as a town in 1839. The town got its name from the early Friends (Quakers) who settled around the area and established several meetinghouses throughout the county, including the important Western Yearly Meeting of Friends in Plainfield. The Friends were "plain" people, and thus the name "Plainfield". The high school continues to honor the Quakers, using the name for the school's mascot.
