D
HistoryA character grade: shown, never part of Polk City’s overall grade.
Few Florida towns list much on the Register (a typical Florida town has 0.0 per 10,000 residents, the U.S. 2.4), so Polk City’s 0.0 sits below most of its state (33% of Florida 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 D to C−. The pre-1940 share is a Census survey estimate (±4.9 points). The founding year is the first post office, not a stated founding date; Wikidata’s 1925 falls in the same era, so the grade doesn’t depend on which one is used.
