Many countries, through the use of censuses, enumerate their populations by languages and by their level of competence in using those languages.

Afghanistan

Pashto and Dari (Persian) are the official languages of Afghanistan; bilingualism is very common. Both are Indo-European languages from the Iranian languages sub-family. Dari has always been the prestige language and a lingua franca for inter-ethnic communication. It is the native tongue of the Tajiks, Hazaras, Aimaks, and Kizilbash. Pashto is the native tongue of the Pashtuns, although many Pashtuns often use Dari and some non-Pashtuns are fluent in Pashto.

Other languages, including Uzbek, Arabic, Turkmen, Balochi, Pashayi, and Nuristani languages (Ashkunu, Kamkata-viri, Vasi-vari, Tregami, and Kalasha-ala), are the native tongues of minority groups across the country and have official status in the regions where they are widely spoken. Minor languages also include Pamiri (Shughni, Munji, Ishkashimi, and Wakhi), Brahui, Hindko, and Kyrgyz. A small percentage of Afghans are also fluent in Urdu, English and other languages.

Algeria

The official language of Algeria is Modern Standard Arabic (literary Arabic), as specified in its constitution since 1963. In addition to this, Berber has been recognized as a "national language" by constitutional amendment since 8 May 2002. 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%. "Mais tous les arabophones d'Algérie parlent l'arabe dialectal ou l'arabe dit algérien (ou ses diverses variétés) pour communiquer entre eux. Autrement dit, à l'oral, c'est l'arabe algérien qui sert de langue véhiculaire, mais à l'écrit, c'est l'arabe classique." 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 and can be regarded as being a de facto co-official language of Algeria. Kabyle, the most spoken Berber language in the country, is taught and partially co-official (with a few restrictions) in parts of Kabylie.

Belgium

In the past, Belgium held a census each ten years, including a language census (nl/fr). Since 1932, the results of this census defined to which official language a municipality belonged (Dutch, French or German). However, this caused a lot of conflicts along the language border, in Brussels and its periphery (due to the Francization of Brussels). The territory of Belgium was consequently divided into four definitive official language areasArticle 4 of the Constitution. and the language census was abolished, effective 1 September 1963. No national language censuses have been held since then.
