HistoryA character grade: shown, never part of Dunwoody’s overall grade.
Georgia towns list more on the Register than most of the country (a typical Georgia town has 10.0 per 10,000 residents, the U.S. 2.4), so Dunwoody’s 1.7 sits near the middle of its state (38% of Georgia towns have fewer) while its 9 historic buildings outnumber those of 75% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from D to C+. The pre-1940 share (±0.4 points) is firm at this size. The founding year is the first post office, not a stated founding date; Wikidata gives 2008.
