The Tibetans with a population of 4,593,100 mostly live in the Tibet Autonomous Region. There are also Tibetan communities in Qinghai, Gansu, Sichuan and Yunnan provinces.

The Tibetan language belongs to the Tibetan sub-branch of the Tibetan-Myanmese language branch of the Chinese-Tibetan language family. According to geographical divisions, it has three major local dialects: Weizang, Kang and Amdo. The Tibetan script, an alphabetic system of writing, was created in the early 7th century. With four vowels and 30 consonants, it is used in all areas inhabited by Tibetans.

The areas where Tibetans live in compact community are mostly highlands and mountainous country studded with snow-capped peaks, one rising higher than the other. The Qinghai-Tibet Plateau rising about 4,000 meters above sea level is run through from west to east by the Qilian, Kunlun, Tanggula, Gangdise and Himalaya mountain ranges. The Hengduan Mountains, descending from north to south, runs across the western part of Sichuan and Yunnan provinces.

Mt. Qomolangma on the Sino-Nepalese border is 8,848 meters above sea level, the highest in the world. The Tibetan areas are crisscrossed by rivers and dotted with lakes.

Animal husbandry is the main occupation in Tibet where there are vast expanses of grasslands and rich sources of water. The Tibetan sheep, goat, yak and pien cattle are native to the Qinghai-Tibet Plateau. The yak is a big and long-haired animal, capable of with-standing harsh weather and carrying heavy loads. Known as the "Boat on the Plateau," the yak is a major means of transport as well as a source of meat. The pien cattle, a crossbreed of bull and yak, is the best draught animal and milk producer. In farming, the fast ripening and cold- and drought-resistant qingke, a kind of highland barley, is the main crop. Other crops include wheat, pea, buckwheat and broad bean. In the warmer places in the river valleys, there are rape, potato, turnip, apple and walnut. People also grow rice and cotton in river valleys in southern Tibet where the weather is very warm.

The dense forests in the Tibetan areas provide shelter for many precious animals such as sunbird, vulture, giant panda, golden-haired monkey, black leaf monkey, bear and ermine. The forests also produce precious medicines such as bear's gallbladder, musk, pilose antler, caterpillar fungus, snow lotus and glossy ganoderma.

These areas are also richly endowed with hydro-power and mineral resources. There are enormous amounts of hydropower and terrestrial heat for generating electricity, and huge reserves of natural gas, copper, iron, coal, mica and sulfur. The landlocked lakes abound in borax, salt, mirabilite and natural soda. Oilfields have been found in recent years in the Qaidam basin in Qinghai and the northern Tibet Plateau.
