What drives Forest Park’s History grade

B
HistoryA character grade: shown, never part of Forest Park’s overall grade.
Few Illinois towns list much on the Register (a typical Illinois town has 0.5 per 10,000 residents, the U.S. 2.4), so Forest Park’s 0.7 sits near the middle of its state (61% of Illinois towns have fewer) while its 1 listings outnumber those of 51% 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 is a Census survey estimate (±4.7 points). Two sources give 1907.

Before modern settlement, the area now known as Forest Park was inhabited by the Potawatomi and other Native American groups. In 1839, French trader Leon Bourassa purchased 160 acres of land where present day Forest Park lies. German immigrant Ferdinand Haase, bought 40 acres of that land from Leon Bourassa in 1851, which eventually became 240 acres. In 1856, John Henry Quick purchased the land, and named it Harlem after his hometown.
The community of Harlem was incorporated in 1884. However, was renamed to Forest Park, and officially incorporated under that name on April 17, 1907.
In 1907, according to Wikidata. Forest Park’s post office opened in 1922, and the census of 1880 counted 923 people here.
