The 1886–1892 Tsarist population figures counted 124,683 Tats in the Russian Caucasus of which 118,165 were located in the Baku Governorate and 3,609 in the Dagestan Oblast. The 1897 Russian Empire census recorded 95,056 Tats, of which 89,519 were in the Baku Governorate and 2,998 in the Dagestan Oblast. The 1926 Soviet census only counted 28,705 Tats of which 28,443 were in the Azerbaijan SSR and 1,237 in the Dagestan ASSR. Arthur Tsutsiev notes that a major portion of Tats in the 1926 census were listed under the categories "Persians" and "Azerbaijani Turks". This was particularly the case within the Azerbaijan SSR, where some 38,327 individuals were recorded as "Turks whose native language is Tat". The 1979 Soviet census counted 22,441 Tats of which 8,848 were located in the Azerbaijan SSR and 7,437 in the Dagestan ASSR.
