People of mixed Thai and Malay ancestry are known as Sam Sam,[5] which forms the bulk of Satun's population but also a significant minority in Phatthalung,[6][7][8] Trang, Krabi, Phang Nga and Songkhla as well as in the Malaysian states of Kedah, Perak and Perlis. Sam Sams are generally adherents of Islam but culturally Thai, although Malay influences are co-dominant.[9] Phuket[10][11] and Ranong,[12] home to a sizeable Muslim population, also has many people who are of Malay descent.[13] A sizeable community also exists in Bangkok itself, having descended from migrants or prisoners who were relocated from the South from the 13th century onwards.[
