Iran is home to approximately 76 million people of dozens of different ethnic backgrounds.
Important ethnic groups include the Persians (51%), Azeris (24%), Mazandarani and Gilaki (8%), Kurds (7%), Iraqi Arabs (3%), and Lurs, Balochis and Turkmens (2% each).
Smaller populations of Armenians, Persian Jews, Assyrians, Circassians, Georgians, Mandaeans, Hazaras, Kazakhs, and Romany also live in various enclaves within Iran.
With increased educational opportunity for women, Iran’s birth rate has declined markedly in recent years after booming in the late 20th century.
Iran also hosts over 1 million Iraqi and Afghan refugees.
