Population Description: The Sonowal Kachari is a large agriculturally based tribal group who is, for the most part, concentrated in the Dibrugarh district in the northeastern region of the state of Assam. The Sonowal Kachari tribe is composed of seven exogamous clans whose societal structure is patrilineal in a hierarchical union with age. Thus, the eldest male has the highest status in the tribe. The Sonowal Kachari are primarily devout followers of Mohapurisia Baisnav Dharma.

Sonowal Kacharis are a Bodo tribe and belong to the Tibetoburman language family. Other Kachari groups such as the Bodo, Jharua, Thengal etc., still speak the Bodo language. However, the Sonowals have spoken the the Assamese language for many years because they have been surrounded by Assamese speaking caste populations. Therefore, they now speak Assamese.
