The Miami Metropolitan Area is by far the largest urban economy in Florida and the 12th largest in the United States with a GDP of $344.9 billion .

Florida is home to 51 of the world's billionaires with most of them residing in South Florida.
Today, Florida is distinctive for its large Cuban expatriate community and high population growth, as well as for its increasing environmental issues. The state's economy relies mainly on tourism, agriculture, and transportation, which developed in the late 19th century. Florida is also renowned for amusement parks, orange crops, winter vegetables, the Kennedy Space Center, and as a popular destination for retirees. Florida is the flattest state in the United States. Lake Okeechobee is the largest freshwater lake in the U.S. state of Florida.
Human habitation in the southern portion of the Florida peninsula dates to 15,000 years ago. Before European colonization, the region was dominated by the native Calusa and Tequesta tribes. With Spanish colonization, both tribes declined gradually during the following two centuries. The Seminole, formed from mostly Creek people who had been warring to the North, assimilated other peoples and created a new culture after being forced from northern Florida into the Everglades during the Seminole Wars of the early 19th century. After adapting to the region, they were able to resist removal by the United States Army.
Migrants to the region who wanted to develop plantations first proposed draining the Everglades in 1848, but no work of this type was attempted until 1882. Canals were constructed throughout the first half of the 20th century, and spurred the South Florida economy, prompting land development. In 1947, Congress formed the Central and Southern Florida Flood Control Project, which built 1,400 miles (2,300 km) of canals, levees, and water control devices. The Miami metropolitan area grew substantially at this time and Everglades water was diverted to cities. Portions of the Everglades were transformed into farmland, where the primary crop was sugarcane. Approximately 50 percent of the original Everglades has been developed as agricultural or urban areas.
