Aimaks were originally known as chahar ("four") Aymaqs: the Taimani (the main element in the population of Ghor), the Firozkohi, the Temuri, and the Jamshidi. Other sources state that the Aimaq Hazara are one of the Chahar, with the Temuri instead being of the "lesser Aimaqs" or Aimaq-e digar ("other Aimaqs") along with the Tahiri, Zuri, Maleki, and Mishmast.
Aimaks are closely related to Tajiks and Hazaras in varying degrees. In the Afghan census, Aimaks are classified as Tajiks. Aimaks live in parts of western and central Afghanistan, making up the majority in Ghor, and also live in large numbers in the western areas of Herat and Badghis, and to a lesser extent in Farah, Faryab, Jowzjan, and Sar-e Pol. The word "Aymāq" is Mongolian meaning "tribe" or "grazing territory". Aimaq Hazara and Taimuri are most Mongoloid of the Aimaqs. The Temuri and Aimaq Hazaras live in yurts, whereas other Aimaqs live in traditional Afghan black tents.
Estimates of the Aimaq population vary between 250,000 and 0.5 million. They are largely Sunni Muslims, in contrast to the Hazara, who are mostly Shias. The Temuri Aimaqs are of Mongolian origin, apparent in their physical appearance and their housing (Mongolian-style yurts). However, the Taimanis, Ferozkohis, and Jamshidis are of Iranian origin, and refer to themselves as Tajik; the majority of the Aimaqs in Afghanistan are of these latter three sub-groups.
