What drives Lithonia’s History grade
On its age, its old homes and the National Register, Lithonia is more historic than 91% of U.S. towns, #11 of 263 in Georgia. All 3 inputs are above most U.S. towns; its National Register listings ranks highest and its share of homes from before 1940 lowest.
A
HistoryA character grade: shown, never part of Lithonia’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 Lithonia’s 1,316 sits above most of its state (97% of Georgia towns have fewer) while its 345 historic buildings outnumber those of 96% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from A− to A+. The pre-1940 share is a Census survey estimate (±9.3 points). The founding year is the first post office, not a stated founding date.
