The Tulu language (Tuḷu Bāse, Tigalari script: , Kannada script: ತುಳು ಬಾಸೆ, Malayalam script: തുളു ബാസെ; pronunciation in Tulu: [t̪uɭu baːsɛ]) is a Dravidian language whose speakers are concentrated in Dakshina Kannada and in the southern part of Udupi of Karnataka in south-western India and also in the northern parts of the Kasaragod district of Kerala. The native speakers of Tulu are referred to as Tuluva or Tulu people and the geographical area is unofficially called Tulu Nadu.
The Indian census of 2011 reported a total of 1,846,427 native Tulu speakers in India while the 2001 census had reported a total of 1,722,768 native speakers. There is some difficulty in counting Tulu speakers who have migrated from their native region as they are often counted as Kannada speakers in Indian census reports.
