This extensive survey documents Tibetan society over five decades, including population structure in rural and urban areas, marriage and migration patterns, the maintenance of language and traditional culture, economic transitions relating to income and consumption habits, educational development, and the growth of civil society and social organizations. In addition to household surveys completed over twenty years, the book provides a systematic analysis of all available social and census data released by the Chinese government, and a thorough review of Western and Chinese literature on the topic. It is the first book on Tibetan society published in English by a mainland China scholar, and covers several sensitive issues in Tibetan studies, including population changes, Han migration into Tibetan areas, intermarriage patterns, and ethnic relations.
