Hill people and minority cultures of Laos such as the Hmong, Yao (Mien) (Hmong-Mien), Dao, Shan, and several Tibeto-Burman speaking peoples have lived in isolated regions of Laos for many years. Mountain/hill tribes of mixed ethno/cultural-linguistic heritage are found in northern Laos, which include the Lua and Khmu people who are indigenous to Laos. Collectively, they are known as Lao Soung or highland Laotians. Lao Soung account for about 10% of the population.
