There are numerous ethnic groups in Bhutan, and no one group constitutes a majority of the Bhutanese population. The Bhutanese are of four main ethnic groups, which themselves are not necessarily exclusive: the politically and culturally dominant Ngalop of western and northern Bhutan; the Sharchop of eastern Bhutan; the Lhotshampa concentrated in southern Bhutan; and Bhutanese tribal and aboriginal peoples living in villages scattered throughout Bhutan.
