Sierra Leone officially the Republic of Sierra Leone, is a country in West Africa. It is bordered by Guinea to the north-east, Liberia to the south-east and the Atlantic Ocean to the south-west. Sierra Leone has a tropical climate, with a diverse environment ranging from savannah to rainforests. The country has a total area of 71,740 km2 (27,699 sq mi) and a population of 7,075,641 (based on the 2015 national census).

Sierra Leone is made up of five administrative regions: the Northern Province, Northwestern Province, Eastern Province, Southern Province and the Western Area, which are subdivided into sixteen districts. Each district has its own directly elected local government, though with limited power, as most of the powers are held by the central government in Freetown.
