Miao is a word used in modern China to designate a category of ethnic groups living in southern China and Mainland Southeast Asia. The Miao are the largest ethnic minority group in China without an autonomous region. The Miao live primarily in the mountains of southern China encompassing the provinces of Guizhou, Yunnan, Sichuan, Hubei, Hunan, Guangxi, Guangdong, and Hainan. Some sub-groups of the Miao, most notably the Hmong people, migrated out of China into Southeast Asia. Following the communist takeover of Laos in 1975, a large group of Hmong refugees resettled in several Western nations, mainly in the United States, France, and Australia.
