The Shan people (; , ; ), also known as the Dai or Tai Yai, are a Tai ethnic group of Southeast Asia. The Shan are the biggest minority of Burma (Myanmar) and primarily live in the Shan State of this country, but also inhabit parts of Mandalay Region, Kachin State, and Kayin State, and in adjacent regions of China (Dai people), Laos, Assam (Ahom people) and Thailand. Though no reliable census has been taken in Burma since 1935, the Shan are estimated to number 4–6 million, with CIA Factbook giving an estimate of five million spread throughout Myanmar which is about 10% of the overall Burmese population.
