1.6 million people is certainly significant, so you're not wrong. But leaving it at that without more information is likely to mislead people. > The CIA World Factbook (which is based on 2013 statistics) gives the following numbers for the languages spoken in Iran today: Persian, Luri, Gilaki and Mazandarani 66%; Azerbaijani and other Turkic languages 18%; Kurdish 10%; Arabic 2%; Balochi 2%; others 2% (Armenian, Georgian, Circassian, Assyrian, etc.).[20] > Other sources, such as the Library of Congress, and the Encyclopedia of Islam (Leiden)[21] give Iran's ethnic groups as following: Persians 65%, Azerbaijanis 16%, Kurds 7%, Lurs 6%, Arabs 2%, Baloch 2%, Turkmens 1%, Turkic tribal groups (e.g. Qashqai) 1%, and non-Persian, non-Turkic groups (e.g. Armenians, Georgians, Assyrians, Circassians, Basseri ) less than 1%.[22] For sources prior to and after 2000, see Languages and ethnicities in Iran. https://en.wikipedia.org/wiki/Demographics_of_Iran#Languages_and_ethnic_groups https://en.wikipedia.org/wiki/Demographics_of_Iran#Languages...
