HistoryA character grade: shown, never part of St. Clairsville’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 St. Clairsville’s 126 sits above most of its state (94% of Ohio towns have fewer) while its 63 historic buildings outnumber those of 86% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from B+ to A. The pre-1940 share is a Census survey estimate (±5.0 points). Two sources give 1790.
