The Austro-Asiatic language family includes languages spoken in Southeast Asia, Eastern India, and parts of central Asia. Bhumij, Kharia, and Birhor are part of this family.
Bhumij, Kharia, and Birhor are members of the Austro-Asiatic language family. Kumaoni, in contrast, is an Indo-Aryan language within the Indo-European family, distinct from the Austro-Asiatic classification.
