D−
HistoryA character grade: shown, never part of Ladson’s overall grade.
South Carolina towns list more on the Register than most of the country (a typical South Carolina town has 3.2 per 10,000 residents, the U.S. 2.4), so Ladson’s 0.0 sits below most of its state (23% of South Carolina towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would still be D−. The pre-1940 share (±0.5 points) is firm at this size. The founding year is the first post office, not a stated founding date.
Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24.
