Tibet is located in southwest China. The people who live there are of different ethnic groups but as many might infer, the Tibetan culture is predominant in that region. There are Tibetans outside the territory of Tibet as well. As journalist Adrienne Mong has pointed out in her blog on the MSNBC website, in Aba Prefecture, neighboring Sichuan province, half of the people there are Tibetans. This makes, according to her data about the net population in Aba Prefecture, about 420 000 people.
