HistoryA character grade: shown, never part of Southgate’s overall grade.
Kentucky towns list more on the Register than most of the country (a typical Kentucky town has 29.9 per 10,000 residents, the U.S. 2.4), so Southgate’s 0.0 sits below most of its state (12% of Kentucky 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 range from C+ to A. The pre-1940 share is a Census survey estimate (±6.7 points). The founding year is the first post office, not a stated founding date.
