Bhutan's population is, in many ways, one large family. About 70 percent of the people still live on subsistence farming, scattered in sparsely populated villages, across the rugged terrain of the Himalayas. Since early days, Bhutanese communities settled in the valleys with limited communication from outside word and perhaps it is for this reason that the sense of individuality andindependence emerges as a strong characteristic of the people. The Bhutanese are, by nature, physically strong and fiercely independent with open and ready sense of humour. Hospitality is an in-built social value in Bhutan. The estimated population of the country is about 7,44,000 and three main ethnic groups constitute its population: Sharchops: live in eastern part of country, recognized as the original inhabitants of Bhutan and are of Indo Mongoloid origin. Ngalops: are descendants of Tibetan immigrants who arrived in Bhutan from 9th century and settled in the west of country. Lhotshampas: this Nepalese group, began settling in the south of Bhutan in the late 19th century. The Lhotshampa represents different Nepali speaking ethnic groups primarily – Brahman, Chettri, Gurung, Rai and Limbu.
