The Interior Division (Malay: Bahagian Pedalaman) is an administrative division of the state of Sabah, Malaysia. It occupies the southwest portion of Sabah, bordered by the neighbouring state of Sarawak on its west. With an area of 18,298 square kilometres, it covers 24.9% of Sabah's territory and is home to approximately 14.7% of Sabah's total population.[1] The largest town in the Interior Division is Keningau. Other main towns in this division include Beaufort, Kuala Penyu, Sipitang, Tambunan and Tenom.[1]
The coastal parts of the Division are settled mainly by Bisaya, Bruneian Malays and Kedayan, whereas the inland areas to the east of the Crocker Range are mostly settled by various subgroups of the Dusun people. The town of Tambunan is considered to be a major centre of Dusun culture,[2] while Tenom is the largest town in the heartland of the Murut people.[3] The Long Pasia and Long Mio are the gateway to the Lun Bawang/ Lun Dayeh tribes in Sipitang.[1][4] In addition, there are large numbers of Chinese people in most of the towns, particularly Beaufort, Keningau and Tenom. The majority of the Division's ethnic Chinese residents are of the Hakka subgroup.[5][6]
