Baku Governorate
As late as the turn of the 20th century, the Tat constituted about 11% of the population of the entire eastern half of Azerbaijan (see Baku Governorate, the section on Demography). They formed nearly one-fifth (18.9%) of the population of the Baku province and over one-quarter (25.3%) of the Kuba Province—both on the Caspian Sea. Either through misrepresentation, data manipulation, or simple assimilation, the Tat portion of the population of Azerbaijan has shrunk to insignificance, facing assimilation.
