From Shell People to Seasonal Harvests: The Evolution of Southwest Florida

Countries & Cities · Published 16 October 2026 Swipe more like this →

In short: Long before the 1920s land boom, this coastal area supported the Calusa, a civilization of over 50,000 people. Today, the region maintains a complex balance between a massive winter resort economy and a rural agricultural backbone that produces essential goods like beef, citrus, and sugarcane for the nation.

The human history of Southwest Florida is defined by dramatic shifts in population and land use. Nomadic Paleo-Indians lived throughout this area roughly 10,000 BC, during the final ice age. They were eventually succeeded by the Calusa, known as the "shell people." By the 16th century, the Calusa population had reached over 50,000, thriving along the coast until the arrival of Europeans introduced devastating diseases like smallpox and measles. Until the 1920s Florida land boom occurred, the territory stayed mostly wild. Modern Southwest Florida is now a complex mosaic of environments. While the coast is defined by a winter resort economy and tourism, the inland counties of DeSoto, Glades, and Hendry remain notably rural. These areas serve as an agricultural engine, producing tomatoes, beef, sugarcane, and citrus products. This industry relies heavily on a seasonal workforce of approximately 16,000 workers, 90 percent of whom are estimated to be migrants. Today, the region's infrastructure is designed to support both high-volume travel and local commerce. It is served by major arteries like the Tamiami Trail and Interstate 75, connecting the coast to Tampa and Greater Miami. Southwest Florida International Airport anchors this aviation centre, hosting 10.3 million travellers in 2021 and ranking among the 50 most active US airports. This infrastructure facilitates a diverse economy ranging from international travel to the regional freight services provided by the Seminole Gulf Railway.
