The Karen, also known as the Kayin, Kariang or Kawthoolese, are an ethnolinguistic group of Sino-Tibetan language–speaking peoples. The group as a whole is heterogeneous and disparate as many Karen ethnic groups do not associate or identify with each other culturally or linguistically. These Karen groups reside primarily in Kayin State, southern and southeastern Myanmar. The Karen, approximately five million people, account for approximately seven percent of the Burmese population. Many Karen have migrated to Thailand, having settled mostly on the Myanmar–Thailand border. A few Karen have settled in the Andaman and Nicobar Islands, India, and other Southeast Asian and East Asian countries.
