Ethnics
Sebauh District is home to Iban, Chinese, Melanau, Malay and Ulu people. Most Ibans are scattered throughout rural areas of Sebauh, namely in Pandan, Labang, Tubau and Kakus. Melanau people (or Melanau Bintulu/Vaie people) are concentrated at Sebauh town and rural communal areas, namely at Pandan and Labang. Many Malay people are not originally from Sebauh, however, intermarriage with locals especially Melanau people has made Malay as one of the major ethnics in Sebauh. Chinese people are more concentrated at Sebauh town, while some reside in the rural areas of Kuala Kebulu and Jelalong. Orang Ulu people, such as Kenyah, Kayan, Tatau, Penan and Punan are more scattered throughout Sebauh District compared to Iban people. Most of them still live in rural areas like Kakus and Jelalong.
