Since the Chinese Family Planning Program is not carried out among the peoples (except the Han Chinese) in Tibet, the population keeps growing. Till the end of 2003, its population has amounted to 2,701,700, among which are 2,507,200 Tibetans, 92.8 percent of the total population.
Tibetans are optimistic and forthright people, adept in singing and dancing. The language they speak belongs to the Sino-Tibetan phylum, and people in U, Tsang, Kham, Chamdo and Amdo speak different dialects. Generally, most farmers live in small villages and earn their living by farming, and the nomads live by herding yaks and sheep. Tibetans in cities are mainly engaged in producing handicrafts, industry and business. Most Tibetans are devout Buddhists. The old Bon, Islam and Catholicism also have a few followers respectively.
Besides Tibetans, Menpa, Luopa, Sherpa, and Deng are also the main aborigines in Tibet. Most of the Menpa people inhabit in the south of Tibet. They mainly earn their living by farming, with a few engaged in stock raising, hunting and handicraft industry. A special feature of Menpa is that every adult male carries a broadsword beside his waist. All the males and females of Menpa like alcohol and snuff. The Luopa people mainly live in the southeast of Tibet. Most of them live by farming. The Luopa people are very skillful. Their handworks plaited with bamboo are exquisite. Both of the two races only have oral language, no written one. Most of them believe in their own aboriginal religion, with a few as Buddhists. Though monogamous marriage is the main marriage form, polygamy still exists. In the past, they had behindhand economy and medical treatment due to the poor transportation of their regions. Now the state is rapidly improving under the support of government.
The Sherpa people mainly live in Dingkye and Nyalam of Shigatse . Sherpa means oriental in Tibetan. Most of the Sherpa people are Buddhists and engaged in farming and boarder trade. Compared with other races, Deng has a relatively smaller population. The Deng people mainly live in Dzayul, southeast of Tibet. They believe in ghost, not god. The Deng people have their own language, but neither Sherpa nor Deng has written language. The Deng people keep a record of events by knotting ropes or making marks on wood. Han Chinese is the second largest population in Tibet. Most of them are cadres and technicians dispatched to Tibet to help its development. Most of the Hui People now living in Tibet are those who immigrated there from other provinces during the Qing Dynasty (1644-1911), mainly engaged in business, handicraft industry and butchering. Other races in Tibet, such as Naxi, Nu, etc., mainly live in cities, with a small population respectively.
