Caste-wise percentage in Assam

Assam has a highly diverse social structure made up of several castes, tribes, and ethnic communities. Among the forward or general category groups, Kalita is one of the most prominent communities and is traditionally placed socially between the Keot and priestly groups, such as Brahmins and Ganak (astrologers). The Keot community has historically been associated with agriculture and river-based occupations. 

Other influential communities in the state include the Ahom and Koch-Rajbongshi, both of which have played an important role in the region’s history and society. In addition, indigenous communities such as Moran, Muttock, Sutia, and Adivasi (Tea Garden tribes) also form an important part of Assam’s social and cultural landscape.

Tribal communities make up roughly 12.45% of the population. The most prominent among them are the Bodo (Boro) people, one of the largest indigenous ethnolinguistic groups concentrated mainly in the Bodoland region. Other important tribal groups include Karbi, Rabha, Mishing, Dimasa, and Deori

Scheduled Castes account for about 7.15% of Assam’s population, with major communities including Kaibartta (Jaliya), Jhalo-Malo, and Namasudra, many of whom traditionally depended on fishing and allied occupations.

Note: The Government of India has not enumerated caste-wise population data other than Scheduled Castes (SCs) and Scheduled Tribes (STs) in the Census 2011. Therefore, estimates for Other Backward Classes (OBC) vary and are based on different studies and approximations.
