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 3.6 inhabitants per square kilometre (9.3/sq mi). (Its population is less than 1/200 the population 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 primevalrainforest. The Guiana Amazonian Park, which is the largest national park in the European Union, covers 41% of French Guiana's territory.
