Many local languages are dialects and/or
endangered. The
Dari language functions as the nation's
lingua franca and is the native tongue of several of Afghanistan's ethnic groups including the
Tajiks,
Hazaras, and
Aimaqs. Pashto is the
native tongue of the
Pashtuns, the dominant ethnic group in Afghanistan. Due to Afghanistan's
multi-ethnic character,
multilingualism is a common phenomenon. The exact figures about the size and composition of the various ethnolinguistic groups are unavailable since no systematic census has been held in Afghanistan in decades. The table below displays estimates of the major languages spoken in Afghanistan per sample statistics: Statistics vary considerably from source to source, the amount of total Dari (L1+L2) speakers tends to be the most consistent (77-80%). Between sources the amount of L1 speakers of Pashto and Dari vary considerably. With
Encyclopedia Britannica estimating that roughly 1/2 of the population of Afghanistan speaks Dari natively, and "more than" 2/5 of Afghanistan speaking Pashto natively. While estimating a lower amount of native Pashto speakers then other sources, Britannica estimates that roughly 20% of the population spoke Pashto as a second language (an estimate higher that most other sources). Britannica also notes that many Pashtuns (particularly in urban areas) speak Dari as their first language, so the quantity of first language speakers is not a reliable indication of ethnicity. Other sources may give higher estimates for L1 Pashto speakers but lower estimates for L2 speakers, and may give varying estimates for Dari depending on whether regional varieties of Dari such as
Hazaragi and
Aimaqi are counted as languages or dialects.
Encyclopedia Iranica estimates that 50-55% of Afghanistan speak Pashto as their native language, but estimates few second language speakers (no estimate was given, only that the amount of L2 speakers was "less than 10%"). Iranica also estimated 25% of Afghanistan natively speaking Dari but also categorized varieties of Persian spoken in central Afghanistan as different languages from Dari, and gave no estimates to the percentage of non-Dari Persian speakers. Iranica also made no reference to how many ethnic Pashtuns spoke Dari as their first language. A sizeable population in Afghanistan, especially in
Kabul, can also speak and understand
Urdu due to the mass migration of Afghan refugees during the
Soviet–Afghan War. == Language policy ==
