HistoryA character grade: shown, never part of Oak Ridge’s overall grade.
North Carolina towns list more on the Register than most of the country (a typical North Carolina town has 12.5 per 10,000 residents, the U.S. 2.4), so Oak Ridge’s 47.8 sits above most of its state (68% of North Carolina towns have fewer) while its 37 historic buildings outnumber those of 83% 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 (±0.8 points) is firm at this size. The founding year is the first post office, not a stated founding date; Wikidata gives 1998.
