The Cameroon government held two national censuses during the country's first 44 years as an independent country, in 1976 and again in 1987. Results from the second head count were never published. A third census, expected to take years to produce results, began on November 11, 2005, with a three-week interviewing phase. It is one of a series of projects and reforms required by the International Monetary Fund as prerequisites for foreign debt relief. The first results were published in 2010.
According to the 2010 revision of the World Population Prospects the total population was 19 599 000 in 2010, compared to only 4 466 000 in 1950. The proportion of children below the age of 15 in 2010 was 40.6%, 55.9% was between 15 and 65 years of age, while 3.5% was 65 years or older.

There are 24 major African language groups in Cameroon; additionally, English and French are official languages. Cameroonian Pidgin English is also widely spoken.
Peoples concentrated in the Southwest and Northwest Provinces — around Buea and Bamenda — use standard English and Cameroonian Pidgin English, as well as their local languages. In the three northern provinces — Adamawa, North, and Far North — either French or Fulfulde (the language of the Fulani) is widely spoken. Elsewhere, French is the principal second language, although pidgin and some local languages such as Ewondo, the dialect of a Beti clan from the Yaoundé area, have a wide currency.
