What drives Oak Ridge’s History grade

On its age, its old homes and the National Register, Oak Ridge is more historic than 58% of U.S. towns, #113 of 290 in North Carolina. Its National Register listings hold the grade up; its share of homes from before 1940 pulls it down.

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.

Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24.
