HistoryA character grade: shown, never part of Oak Grove’s overall grade.
South Carolina towns list more on the Register than most of the country (a typical South Carolina town has 3.2 per 10,000 residents, the U.S. 2.4), so Oak Grove’s 0.0 sits below most of its state (23% of South Carolina towns have fewer) while its 0 listings outnumber those of 23% 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 (±0.3 points) is firm at this size.
