Yaoundé (/ˌjɑːuːnˈdeɪ/ or /jaːˈʊndeɪ/, French pronunciation: [ja.un.de]; German: Jaunde) is the capital of Cameroon and, with a population of approximately 2.5 million, the second largest city in the country after the port city Douala. It lies in the centre of the nation at an elevation of about 750 metres (2,500 ft) above sea level.
The country has four patterns of drainage. In the south, the principal rivers flow southwestward or westward directly to the Gulf of Guinea — the Wouri, and lesser Dibamba, Bimbia and Mungo to the Cameroon estuary near Douala; Sanaga, Nyong, and Ntem further south along the coast; Akwayafe and Manyu (which joins Nigerian Cross), and the lesser Ndian and Meme in the north of coast.
Education is free in state schools and compulsory between ages 6 and 12. Government funds are available to mission and private schools. Most secondary schools have been made bilingual, with instruction in both French and English. Working alongside the public schools are the missionary schools, which have been extremely important in the history of Cameroonian education. As of 1999, public expenditure on education was estimated at 2.6% of GDP.
