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 official languages of Algeria are Modern Standard Arabic (literary Arabic) and Tamazight (Berber), as specified in its constitution since 1963 for the former and since 2016 for the latter. Berber has been recognized as a "national language" by constitutional amendment since 8 May 2002. In February, 2016, a constitutional resolution was passed making Berber an official language alongside Arabic. Algerian Arabic and Berber are the native languages of over 99% of Algerians, with Algerian Arabic spoken by about 72% and Berber by 27.4%. French, though it has no official status, is widely used in government, culture, media (newspapers) and education (from primary school), due to Algeria's colonial history. Kabyle, the most spoken Berber language in the country, is taught and partially co-official (with a few restrictions) in parts of Kabylie.
