Algeria
Islam is the predominant religion in Algeria, with its adherents, mostly Sunnis, accounting for 99% of the population according to a 2012 CIA World Factbook estimate, and 97.9% according to Pew Research in 2010. There are about 150,000 Ibadis in the M'zab Valley in the region of Ghardaia.
Languages of Algeria
The 1963 constitution of Algeria made Arabic the official language, and this was retained in the 1976 constitution. The 1976 constitution states in Article 3 "Arabic is the national and official language". Neither constitution mentions Berber. The Permanent Committee on Geographical Names for British Official Use (PCGN) stated "Arabic was chosen at the outset as the language which was to represent Algeria’s identity and religion, and official attitudes towards both Berber and French have been largely negative." The PCGN stated that French, not Arabic, is the actual lingua franca of Algeria. Arabic is not commonly used in the Kabylie region.
