French Guiana has two districts ( arrondissements ): Cayenne, the coastal region, where more than 90% of the population is concentrated; and the larger interior district of Saint Laurent-du-Maroni. The population is largely of mixed African and European descent, but there are also minorities of blacks, whites, indigenous peoples, Chinese, and South Asians. French is the official language, but Creole and other languages and dialects are spoken as well. The population is predominantly Roman Catholic.
French Guiana is largely dependent on subsidies and imports from the mother country. Fishing and forestry are the prime industries, and timber, shrimp, and rum made from local sugarcane are the chief exports. Rice, corn, bananas and other fruits, vegetables, and manioc are grown for subsistence. There are gold (discovered in 1855), petroleum, and other mineral deposits; exploitation, however, has been hindered by inadequate transportation and scarcity of labor. The Plan Vert (Green Plan), adopted in the late 1970s to increase production in agriculture and forestry, met with only partial success.
The department (also one of 26 official regions of France) is represented in the French National Assembly and Senate. It is governed by a prefect and an elected council.
