HistoryA character grade: shown, never part of Edison’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 Edison’s 164 sits above most of its state (78% of Georgia towns have fewer) while its 22 historic buildings outnumber those of 80% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from B− to A−. The pre-1940 share is a Census survey estimate (±7.6 points). The founding year is the first post office, not a stated founding date.
