Bhutanese are mainly of Tibetan stock, and are also known as Buotias; they account for approximately 50% of the population. The Ngalop (also called Bhote) are people of Tibetan origin who live in northern and western Bhutan; the Sharchop inhabit the eastern regions and also have ethnic affinities with the people of China's Tibetan region. Aboriginal or indigenous tribal peoples live in villages scattered throughout Bhutan and account for approximately 15% of the population. The remaining peoples are Nepalese settlers (about 35% of the population), living mostly in the south. Some 85,000 were expelled to Nepal in 1992–93, and about 5,000–15,000 more moved to India.
