HistoryA character grade: shown, never part of Jackson Township’s overall grade.
Ohio towns list about as much on the Register as the country (a typical Ohio town has 2.9 per 10,000 residents, the U.S. 2.4), so Jackson Township’s 12.9 sits above most of its state (77% of Ohio towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.
How sure. Graded on two of the three inputs, so a change in either one moves the letter more than it would with three. The pre-1940 share is a Census survey estimate (±3.5 points).

Established in 1817, residents named the town after Andrew Jackson, a hero of the War of 1812, and an eventual president of the United States. The community grew slowly, having only 297 inhabitants in 1840. In 1846, Jackson had four churches, about seven stores, and a single newspaper office. Over the next 40 years, the town grew quickly, attaining a population of 3,021 people in 1880. By 1880, two railroad lines passed through the community, helping to spur economic and population growth. In 1886, two newspaper offices, eight churches, and two banks existed in Jackson. The largest businesses in the town were the Star Furnace Company and the Globe Iron Company, with 30 employees apiece. Both firms used local coal and iron ore deposits to make iron products.
