↑Elling, Rasmus Christian. Minorities in Iran: Nationalism and Ethnicity after Khomeini, Palgrave Macmillan, 2013. Excerpt: "The number of Azeris in Iran is heavily disputed. In 2005, Amanolahi estimated all Turkic-speaking communities in Iran to number no more than 9 million. CIA and Library of congress estimates range from 16 to 24 percent—that is, 12–18 million people if we employ the latest total figure for Iran's population (77.8 million). Azeri ethnicsts, on the other hand, argue that overall number is much higher, even as much as 50 percent or more of the total population. Such inflated estimates may have influenced some Western scholars who suggest that up to 30 percent (that is, some 23 million today) Iranians are Azeris."
