This article focuses on the status of ethnic minorities in contemporary Iran.
The majority of the Iranian population is formed by the Persians (estimated at between 51% and 65%). The largest other ethno-linguistic groups (accounting for more than 1% of the total population each) are: Azerbaijanis (16–25+%), Kurds (7–10%), Lurs (c. 7%), Mazandaranis and Gilakis (c. 7%), Arabs (2–3%), Balochi (c. 2%) Turkmens (c. 2%).
There are numerous minor groups, various tribal Turkic groups (Qashqai, Afshar, etc.) accounting for about 1% of the population between them, and small groups with presence in the region going back at least several centuries, accounting for 1-2% as well, such as the Talysh, Armenians, Georgians, Assyrians, Jews, and Circassians.
Furthermore, there are recent immigrant groups, arriving in the 20th to 21st century, such as Russians, Turks, Koreans, Iraqis, etc.
Some of the main ethnic groups in Iran are also religious minorities. For instance, the majority of Kurds, Baluchis and Turkmen are Sunni Muslims and the Armenians are Christian, while the state religion in Iran is Shi'a Islam. Some of these groups, however, have large Shi'a minorties, and the overwhelming majority of Persians and Azeris are Shi'a.
