The Tibetan diaspora is a term used to refer to the communities of Tibetan people living outside their original homeland of Tibet. Tibetan emigration has three separate stages. The first stage was in 1959 following the 14th Dalai Lama's escape to Dharamsala in India, in fear of persecution from the People's Liberation Army. The second stage occurred in the 1980s, when China opened Tibet to foreigners. The third stage began in 1996 and continues today although with less frequency. Not all emigration from Tibet is permanent; today some parents in Tibet send their children to communities in the diaspora to receive a traditional Tibetan education. The 2009 census registered about 128,000 Tibetans in exile, with the most numerous part of the community living in India, Nepal, and Bhutan. However, in 2005 and 2009 there were estimates of up to 150,000 living in exile.
The Central Tibetan Administration (CTA) provides a Green Book - a kind of Tibetan identity certificate - to Tibetan refugees. Based on a CTA survey from 2009, 127,935 Tibetans were registered in the diaspora: in India 94,203; in Nepal 13,514; in Bhutan 1,298; and in rest of the world 18,920. However, their number is estimated at up to 150,000, as mentioned by both Edward J. Mills et al. in 2005 and by the 14th Dalai Lama in 2009.
The larger of the other communities are in the United States, Canada, the United Kingdom, Switzerland, Norway, France, Taiwan and Australia.
During the 1959 Tibetan uprising, the 14th Dalai Lama and some of his government fled to India. From 1959 to 1960, about 80,000 Tibetans followed the Dalai Lama to India through the Himalayas. Continued flights, estimated in the numbers of 1,000 to 2,500 a year, increased these numbers to 100,000. The movement of refugees during this time is sometimes referred to as an "exodus", as in a United Nations General Assembly resolution in 1961 that asserted that the presence of Tibetan refugees in neighboring countries was "evidence" of rights abuses in Tibet.
