Ethnic Groups and Religion Of Iranian

As with the spoken languages, the ethnic group composition also remains a point of debate, mainly regarding the largest and second-largest ethnic groups, the Persians and Azerbaijanis, due to the lack of Iranian state censuses based on ethnicity. The CIA's World Factbook has estimated that around 79% of the population of Iran are a diverse Indo-European ethno-linguistic group that comprise the speakers of the Iranian languages,[340] with Persians (incl. Mazenderanis and Gilaks) constituting 61% of the population, Kurds 10%, Lurs 6%, and Balochs 2%. Peoples of other ethno-linguistic groups make up the remaining 21%, with Azerbaijanis constituting 16%, Arabs 2%, Turkmens and other Turkic tribes 2%, and others (such as Armenians, Talysh, Georgians, Circassians, Assyrians) 1%.

The Library of Congress issued slightly different estimates: 65% Persians (incl. Mazenderanis, Gilaks, and the Talysh), 16% Azerbaijanis, 7% Kurds, 6% Lurs, 2% Baloch, 1% Turkic tribal groups (incl. Qashqai and Turkmens), and non-Iranian, non-Turkic groups (incl. Armenians, Georgians, Assyrians, Circassians, and Arabs) less than 3%. It determined that Persian is the first language of at least 65% of the country's population, and is the second language for most of the remaining 35%.

Other non-governmental estimations regarding the groups other than the Persians and Azerbaijanis roughly congruate with the World Factbook and the Library of Congress. However, many scholarly and organisational estimations regarding the number of these two groups differ significantly from the mentioned census. According to many of them, the number of ethnic Azerbaijanis in Iran comprises between 21.6–30% of the total population, with the majority holding it on 25%.c In any case, the largest population of Azerbaijanis in the world live in Iran.



Historically, early Iranian religions such as the Proto-Iranic religion and the subsequent Zoroastrianism and Manichaeism were the dominant religions in Iran, particularly during the Median, Achaemenid, Parthian, and Sasanian eras. This changed after the fall of the Sasanian Empire by the centuries-long Islamization that followed the Muslim Conquest of Iran. Iran was predominantly Sunni until the conversion of the country (as well as the people of what is today the neighboring Republic of Azerbaijan) to Shia Islam by the order of the Safavid dynasty in the 16th century.

Today, Twelver Shia Islam is the official state religion, to which about 90% to 95% of the population adhere. About 4% to 8% of the population are Sunni Muslims, mainly Kurds and Baloches. The remaining 2% are non-Muslim religious minorities, including Christians, Jews, Bahais, Mandeans, Yezidis, Yarsanis, and Zoroastrians.

Judaism has a long history in Iran, dating back to the Achaemenid Conquest of Babylonia. Although many left in the wake of the establishment of the State of Israel and the 1979 Revolution, about 8,756 to 25,000 Jewish people live in Iran. Iran has the largest Jewish population in the Middle East outside of Israel.

Around 250,000 to 370,000 Christians reside in Iran, and Christianity is the country's largest recognized minority religion. Most are of Armenian background, as well as a sizable minority of Assyrians.[358]

Christianity, Judaism, Zoroastrianism, and the Sunni branch of Islam are officially recognized by the government, and have reserved seats in the Iranian Parliament.[138] But the Bahá'í Faith, which is said to be the largest non-Muslim religious minority in Iran, is not officially recognized, and has been persecuted during its existence in Iran since the 19th century. Since the 1979 Revolution, the persecution of Bahais has increased with executions and denial of civil right

The government has not released statistics regarding irreligiosity. However, irreligious figures are growing and are higher in the diaspora, notably among Iranian Americans.
