Tajik
Tajiks, also khown as Tadzhiks, Tazi or Tadjiks, are a group of various Persianate Eastern Iranian groups of people native to Central Asia, living mainly in Afghanistan, Tajikistan and Uzbekistan. Even though the term Tajik does not refer to a cohesive cross-national ethnic group, Tajiks are the largest ethnicity in Tajikistan, and the second-largest in both Afghanistan and Uzbekistan. They speak variations of Persian, a west Iranian language. In Tajikistan, since the 1939 Soviet census, its small Pamiri and Yaghnobi ethnic groups are included as Tajiks. In China, the term is used to refer to its Pamiri ethnic groups, the Tajiks of Xinjiang, who speak the Eastern Iranian Pamiri languages. In Afghanistan, the Pamiris are considered a separate ethnic group.
