Demographics of Nepal

The Nepalese are descendants of three major migrations from India, Tibet, and North Burma and Yunnan via Assam.
Among the earliest inhabitants were the Kirat of east mid-region, Newar of the Kathmandu Valley and aboriginal Tharu in the southern Terai region. The ancestors of the Brahman and Chetri caste groups came from India's present Kumaon, Garhwal and Kashmir regions, while other ethnic groups trace their origins to North Burma and Yunnan and Tibet, e.g. the Gurung and Magar in the west, Rai and Limbu in the east (from Yunnan and north Burma via Assam), and Sherpa and Bhutia in the north (from Tibet).
In the Terai, a part of the Ganges Basin with 20% of the land, much of the population is physically and culturally similar to the Indo-Aryans of northern India. Indo-Aryan and East Asian looking mixed people live in the hill region. Indo-Aryan ancestry has been a source of prestige in Nepal for centuries, and the ruling families have been of Indo-Aryan and Hindu background. The mountainous highlands are sparsely populated. Kathmandu Valley, in the middle hill region, constitutes a small fraction of the nation's area but is the most densely populated, with almost 5% of the population.
Nepal is a multilingual society. These data are largely derived from Nepal's 2001 census results published in the Nepal Population Report 2002.
According to the World Refugee Survey 2008, published by the U.S. Committee for Refugees and Immigrants, Nepal hosted a population of refugees and asylum seekers in 2007 numbering approximately 130,000. Of this population, approximately 109,200 persons were from Bhutan and 20,500 from People's Republic of China. The government of Nepal restricted Bhutanese refugees to seven camps in the Jhapa and Morang districts, and refugees were not permitted to work in most professions. At present, the United States is working towards resettling more than 60,000 of these refugees in the US.

Despite the migration of a significant section of the population to the southern plains or terai in recent years, the majority of the population still lives in the central highlands. The northern mountains are sparsely populated.
Kathmandu, with a population of around 800,000 (metropolitan area: 1.5 million), is the largest city in the country.
