Togo (officially the Togolese Republic) is a narrow country in West Africa bordering Ghana to the west, Benin to the east and Burkina Faso to the north. It extends south to the Gulf of Guinea, on which the capital Lomé is located. The official language is French; however, there are many other languages spoken in Togo as well. Togo's size is just under 57,000 km². It has a population of more than 6,100,000 people, which is dependent mainly on agriculture.  In the north the land is characterized by a gently rolling savanna in contrast to the center of the country, which is characterized by hills. The south of Togo is characterized by a plateau which reaches to a coastal plain with extensive lagoons and marshes. The land size is 21,925 square miles (56,785 km²), with an average population density of 253 people per square mile (98/km²). In 1914 it changed from Togoland to Togo. The climate is generally tropical with average temperatures ranging from 27°C on the coast to about 30°C in the northernmost regions, with a dry climate and characteristics of a tropical savanna. To the south there are two seasons of rain (the first between April and July and the second between October and November), even though the average rainfall is not very high.
