What drives Conneaut’s History grade
On its age, its old homes and the National Register, Conneaut is more historic than 92% of U.S. towns, #116 of 993 in Ohio. All 3 inputs are above most U.S. towns; its share of homes from before 1940 ranks highest and its National Register listings lowest.

HistoryA character grade: shown, never part of Conneaut’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 Conneaut’s 5.7 sits above most of its state (66% of Ohio towns have fewer) while its 7 listings outnumber those of 73% 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 (±5.1 points). Two sources give 1799.
