Muslims live in every region in China.The highest concentrations are found in the northwest provinces of Xinjiang, Gansu, and Ningxia, with significant populations also found throughout Yunnan province in southwest China and Henan province in central China.Of China’s 55 officially recognized minority peoples, ten groups are predominately Muslim. The largest groups in descending order are Hui (9.8 million in year 2000 census, or 48% of the officially tabulated number of Muslims), Uyghur (8.4 million, 41%), Kazakh (1.25 million , 6.1%), Dongxiang (514,000, 2.5%), Kyrgyz (161,000), Salar (105,000), Tajik (41,000), Uzbeks, Bonan (17,000), and Tatar (5,000). However, individual members of traditionally Muslim ethnic groups may profess other religions or none at all. Additionally, Tibetan Muslims are officially classified along with the Tibetan people, unlike the Hui who are classified as a separate people, even though they are indistinguishable from the Han.Muslims live predominantly in the areas that border Central Asia, Tibet and Mongolia, i.e. Xinjiang, Ningxia, Gansu and Qinghai, which is known as the "Quran Belt".
