French Guiana

French Guiana is an overseas department and region of France on the northern Atlantic coast of South America in the Guianas. It borders Brazil to the east and south and Suriname to the west. French Guiana is the only territory of the mainland Americas to have full integration in a European country. With a land area of 83,534 km2 (32,253 sq mi), French Guiana is the second-largest region of France (it is more than one-seventh the size of Metropolitan France) and the largest outermost region within the European Union. It has a very low population density, with only 3.5 inhabitants per square kilometre (9.1/sq mi). (Its population is less than 1⁄200 that of Metropolitan France.) Half of its 290,691 inhabitants in 2020 lived in the metropolitan area of Cayenne, its capital. 98.9% of the land territory of French Guiana is covered by forests, a large part of which is primeval rainforest. The Guiana Amazonian Park, which is the largest national park in the European Union, covers 41% of French Guiana's territory.
