At 475,440 km2 (183,570 sq mi), Cameroon is the world's 54th largest country. It is slightly larger than the nation of Sweden and state of California. It is comparable in size to Papua New Guinea. Cameroon's landmass is 472,710 km2 (182,510 sq mi), with 2,730 km2 (1,050 sq mi) of water.
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.
The constitution divides Cameroon into 10 semi-autonomous regions, each under the administration of an elected Regional Council. A presidential decree of 12 November 2008 officially instigated the change from provinces to regions.
