Scattered throughout central, southern, and eastern Iran are
small groups speaking many different Indo-Iranian languages. In
the southern part of the Central Plateau are such small nomadic
and seminomadic tribes. Other tribes, related to groups in neighboring
Afghanistan and the Soviet Union, are found in Khorasan. Also
in Khorasan are an estimated 25,000 Tajiks, a settled farming
people related to the Tajiks of Afghanistan and the Soviet Union.
Distinguishable, but comparatively smaller, Indo-Iranian-speaking
minorities are the following tribally organized settled groups:
the Hazareh, Barbai, Teimuri, Jamshidi, and Afghani in Khorasan;
the Qadikolahi and Palavi in Mazandaran; and the Sasani and Agajani
in the Talesh region of Gilan.
