What drives South Palm Beach’s History grade
On its age, its old homes and the National Register, South Palm Beach is more historic than 5% of U.S. towns. Its National Register listings hold the grade up; its share of homes from before 1940 pulls it down.
D−
HistoryA character grade: shown, never part of South Palm Beach’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 South Palm Beach’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 D. The pre-1940 share (±0.4 points) is firm at this size. The founding year is the first post office, not a stated founding date.

The Town of South Palm Beach was first settled by two Finnish brothers from New York in 1948, and was officially incorporated as a municipality in 1955, with several condominiums and four single-family homes platted. Many more condominiums were constructed, contributing to the town's growth in the early 1970s. The fire station served for town meetings until 1993, when a town hall was built.
