Ethnic demography of Kazakhstan
On the other hand, ethnic Kazakhs and Uzbeks have been immigrating in large numbers to Kazakhstan ever since the collapse of the USSR. These immigrants come not only from the southern Central Asian states such as Uzbekistan and Tajikistan, but also from the Kazakh dominated areas in Xinjiang and Mongolia. The Kazakh government is actively encouraging the settlement of these compatriots (known as "Oralman") in Slavic dominated North and East Kazakhstan as well as the German dominated Karaganda Region, in order to dilute the minority populations there. There is also a low intensity immigration of ethnic Slavs from the less tolerant neighboring nations like Uzbekistan and Turkmenistan into Kazakhstan. An estimated 400,000 Uzbeks have migrated to Kazakhstan in recent years
Kazakhs
The Kazakhs are descendants of the Turkic and medieval Mongol tribes – Argyns, Dughlats, Naimans, Jalairs, Keraits, Khazars, Qarluqs; and of the Kipchaks and Cumans, and other tribes such as the Huns and Nogais, and ancient Iranian nomads like the Sarmatians, Saka and Scythians who populated the territory between Siberia and the Black Sea before the 5th and 13th centuries AD.
