According to the 2000 census, the number of Miao in China was estimated to be about 9.6 million. Outside of China, members of the Miao sub-group or nations of the Hmong live in Thailand, Laos, Vietnam and Burma due to outward migrations starting in the 18th century. As a result of recent migrations in the aftermath of the Indochina and Vietnam Wars from 1949–75, many Hmong people now live in the United States, French Guiana, France and Australia. Altogether, there are approximately 10 million speakers in the Miao language family. This language family, which consists of 6 languages and around 35 dialects (some of which are mutually intelligible) belongs to the Hmong/Miao branch of the Hmong–Mien (Miao–Yao) language family.
