Florida Keys are between about 23.5 and 25.5 degrees North latitude,
in the subtropics. The climate of the Keys 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 km). As
of the 2000 census the population was 79,535, with an average density of 579.27
per square mile (223.66 /km), 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.
The city of Key West is the county seat of
Monroe County. The county consists of a section on the mainland which is almost
entirely in Everglades National Park, and the Keys islands from Key Largo to
the Dry Tortugas
