What drives Sanibel’s History grade

On its age, its old homes and the National Register, Sanibel is more historic than 34% of U.S. towns, #141 of 638 in Florida. Its National Register listings hold the grade up; its share of homes from before 1940 pulls it down.

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 Sanibel’s 4.7 sits above most of its state (81% of Florida towns have fewer) while its 3 historic buildings outnumber those of 65% of U.S. towns.

How sure. Graded on any two of the three inputs instead, the letter would range from D to B. The pre-1940 share (±0.4 points) is firm at this size. Two sources give 1884.

Founding year: Wikidata (other dates in Quick answers). Homes: Census ACS 2020–24.

The story

How Sanibel came to be

From Wikipedia’s history of Sanibel.

Read it all →

Sanibel and Captiva formed as one island about 6,000 years ago. The first known humans in the area were the Calusa, who arrived about 2,500 years ago. The Calusa were a powerful Indian nation who came to dominate most of Southwest Florida through trade via their elaborate system of canals and waterways. Sanibel remained an important Calusa settlement until the collapse of their empire, soon after the arrival of the Europeans.

During the 1700s, Cuban fishermen seasonally traveled from their homes and set up fishing camps along the Gulf Coast, called ranchos, including on Sanibel Island.
