Among Turkic peoples[edit]
Modern Kazakh historians claim that more than 2 millions of the Kazakh population are Naimans (see Modern Kazakh tribes or Middle Juz). They originate from eastern Kazakhstan. Some Naimans dissimilated with the Kyrgyz and Uzbek ethnicities and are still found among them.Now, the Naimans are one of the big tribes of modern Kazakh peoples, they belong to Middle Juz of Kazakhs, live mainly in the eastern, central and southern parts of Kazakhstan, with a population of approximately 2 million among Kazakhs in Kazakhstan.

They also exist with considerable population among the Kazakhs in China, Uzbekistan and Russia, the Naiman tribe populations in the Kazakhs in China is one million or more, mostly living in the western part of Xinjiang Uighur Autonomous Region of China, in the Ili Kazakh Autonomous Prefecture. Naimans are also one of the major tribe among Kazakhs in the Uzbekistan, they also exist among Kazakhs in Kyrgyzstan and Russia.And, one of the interesting fact that in the Naiman Shejire (the history of Kazakh tribes) of Kazakhs, it is said that there is a sub-tribe of Naiman tribe of Kazakhs which called Khitan (Kitay or Qitay, Қытай in Kazakh language), this Khitan (Kitay) tribe of Naiman has considerable population among Naimans of Kazakhs, it is approximately estimated that 40% of Naimans of Kazakhs are from this Khitan sub-tribe of Naimans, many Naimans of Kazakh often and commonly trace back their clan roots to this Khitan sub-tribe of Naimans, The Khitan sub-tibe of Naimans branched as Karakerey, Matay, Sadyr and Dortuyl; some Kazakh historians considered this Khitan tribe of Naimans as the Kara Khitan people whose assimilated into Naimans after controlling of Kara Khitan Khanate by Kuchlug and later on during the conquest of Genghis Khan, it can be found many Shejires about Naimans in Kazakh litterateurs and poets. See Naimans introduction in Kazakh language, "Kazakh shezhire".The most recently Y-DNA tests which investigated by KZ DNA Project in Kazakhstan shows that the Y-DNA haplogroup of Naiman tribe of Kazakhs mostly carries O3 and some C, G, N haplogroups see KZ DNA Project.
