Ghana is drained by a large number of streams and rivers. In addition, there are a number of coastal lagoons, the huge man-made Lake Volta, and Lake Bosumtwi, southeast of Kumasi and which has no outlet to the sea.
In 2010, most of the 24.2 million inhabitants were predominantly citizens of the Ashanti (Akan) territories or Ashantiland (Kingdom of Ashanti) (4.7 million in Ashanti, 2.3 million in Brong-Ahafo, 2.2 million in Central, 2.6 million in Eastern, 2.3 million in Western, and 4 million in the seat of government in Greater Accra geographically and legally part of Eastern then administered separately on 23 July 1982).
The climate of Ghana is tropical. The eastern coastal belt is warm and comparatively dry, the south-west corner of Ghana is hot and humid, and the north of Ghana is hot and dry. Ghana is located on the Gulf of Guinea, only a few degrees north of the Equator, giving it a warm climate.
