HistoryA character grade: shown, never part of Flat Rock’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 Flat Rock’s 207 sits above most of its state (84% of North Carolina towns have fewer) while its 22 historic buildings outnumber those of 80% 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 is a Census survey estimate (±14.1 points).

Wikipedia doesn’t have a history of Flat Rock yet. The photos, dates and memories neighbors add here are how it gets written.
Flat Rock is a census-designated place (CDP) in Surry County, North Carolina, United States. The name "Flat Rock" stems from the community's granite quarry. The granite quarry is the largest open-face granite quarry in the world, and has been mined continuously since 1889 by the North Carolina Granite Corporation.
Between the 2010 and 2020 censuses its population fell from 1,556 to 1,326 (-15%).
