Tibetan languages are spoken by some 6 million people. With the worldwide spread of Tibetan Buddhism, the Tibetan language has spread into the western world and can be found in many Buddhist publications and prayer materials; with some western students learning the language for translation of Tibetan texts. Outside Lhasa itself, Lhasa Tibetan is spoken by approximately 200,000 exile speakers who have moved from modern-day Tibet to India and other countries. Tibetan is also spoken by groups of ethnic minorities in Tibet who have lived in close proximity to Tibetans for centuries.
