The last census to be published was held in 1995. Results of every census since then have been kept secret. Available figures indicate that most of Turkmenistan's citizens are ethnic Turkmens with sizeable minorities of Uzbeks and Russians. Smaller minorities include Kazakhs, Tatars, Ukrainians, Kurds (native to the Kopet Dagh mountains), Armenians, Azeris, Balochs and Pashtuns. The percentage of ethnic Russians in Turkmenistan dropped from 18.6% in 1939 to 9.5% in 1989. The ''CIA World Factbook'' estimated the ethnic composition of Turkmenistan in 2003 as 85% Turkmen, 5% Uzbek, 4% Russian and 6% other. According to official data announced in Ashgabat , 91% of the population were Turkmen, 3% were Uzbeks and 2% were Russians. Between 1989 and 2001 the number of Turkmen in Turkmenistan doubled (from 2.5 to 4.9 million), while the number of Russians dropped by two-thirds (from 334,000 to slightly over 100,000). As of 2021, the number of Russians in Turkmenistan was estimated at approximately 100 thousand.
