What drives Seminole’s History grade

On its age, its old homes and the National Register, Seminole is more historic than 14% of U.S. towns, #292 of 638 in Florida. Its age holds the grade up; its share of homes from before 1940 pulls it down.

Florida towns of 2,500+ (638)Ahead of 54%

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 Seminole’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 (±0.3 points) is firm at this size. The founding year is the first post office, not a stated founding date.

The first white settlement at Seminole was made in the 1840s. This community was named after the Seminole tribe, whose descendants still inhabited the area. Seminole was incorporated in 1970. In April 2015, demolition began at Seminole Mall, which was planned to be replaced by the outdoor Seminole City Center.
