The Florida Keys are a coral archipelago in southeast United States. They begin at the southeastern tip of the Florida peninsula, about 15 miles (24 km) south of Miami, and extend in a gentle arc south-southwest and then westward to Key West, the westernmost of the inhabited islands, and on to the uninhabited Dry Tortugas. The islands lie along the Florida Straits, dividing the Atlantic Ocean to the east from the Gulf of Mexico to the west, and defining one edge of Florida Bay. At the nearest point, the southern tip of Key West is just 90 miles (140 km) from Cuba. The Florida Keys are between about 23.5 and 25.5 degrees North latitude, in the subtropics. The climate of the Keys, however, is defined as tropical according to Köppen climate classification. More than 95 percent of the land area lies in Monroe County, but a small portion extends northeast into Miami-Dade County, such as Totten Key. The total land area is 137.3 square miles (356 km²). As of the 2000 census the population was 79,535, with an average density of 579.27 per square mile (223.66 /km²), although much of the population is concentrated in a few areas of much higher density, such as the city of Key West, which has 32% of the entire population of the Keys.

Florida (ⁱ/ˈflɒrɪdə/) is a state in the southeastern United States, bordered to the west by the Gulf of Mexico, to the north by Alabama and Georgia and to the east by the Atlantic Ocean. Florida is the 22nd most extensive, the 4th most populous, and the 8th most densely populated of the 50 United States. The state capital is Tallahassee, its largest city is Jacksonville, and the South Florida metropolitan area is the largest metropolitan area in the southeastern U.S.

Much of Florida is situated on a peninsula between the Gulf of Mexico, the Atlantic Ocean, and the Straits of Florida. Its geography is marked by a coastline, by the omnipresence of water and the threat of hurricanes. Florida has the longest coastline in the contiguous United States, encompassing approximately 1,350 miles (2,170 km), and is the only state to border both the Gulf of Mexico and the Atlantic Ocean. Much of the state is at or near sea level and its terrain is characterized by sedimentary soils. The climate varies from subtropical in the north to tropical in the south. Its symbolic animals like the American alligator, Florida panther and the manatee, can be found in the Everglades, one of the most famous national parks in the world.
