HistoryA character grade: shown, never part of Florida Ridge’s overall grade.
Few Florida State towns list much on the Register (a typical Florida State town has 0.0 per 10,000 residents, the U.S. 2.4), so Florida Ridge’s 1.0 sits above most of its state (72% of Florida State towns have fewer) while its 2 historic buildings outnumber those of 60% of U.S. towns.
How sure. Graded on two of the three inputs, so a change in either one moves the letter more than it would with three. The pre-1940 share (±0.2 points) is firm at this size.
