Ethnic groups

The peoples of Southeast Asia are mainly divided into four major ethnolinguistic groups: the Austronesian, Austroasiatic (or Mon-Khmers), Tai (part of the wider Kra-Dai family) and Tibeto-Burman (part of greater Sino-Tibetan language family) peoples. There is also a smaller but significant number of Hmong-Mien, Chinese, Dravidians, Indo-Aryans, Eurasians and Papuans, which also contributes to the diversity of peoples in the region.

The Aslians and Negritos were believed to be one of the earliest inhabitants in the region. They are genetically related to Papuans in Eastern Indonesia, East Timor and Australian Aborigines. In modern times, the Javanese are the largest ethnic group in Southeast Asia, with more than 100 million people, mostly concentrated in Java, Indonesia. The second-largest ethnic group in Southeast Asia are the Vietnamese (Kinh people) with around 86 million people, mainly inhabiting Vietnam but also forming a significant minority in neighbouring Cambodia and Laos. The Thais are the third largest with around 59 million people, forming the majority in Thailand.

Indonesia is politically and culturally dominated by the Javanese and Sundanese ethnic groups (both native to Java), but the country also has hundreds of ethnic groups scattered throughout the archipelago, such as the Madurese, Minangkabau, Acehnese, Bugis, Balinese, Dayak, Batak, Malay and Ambonese peoples.

In Malaysia, the country is demographically divided into Malays, who make up more than half of the country's population; the Chinese, at around 22%; other Bumiputeras, at 12%; and Indians, at around 6%. In East Malaysia, the Dayaks (mainly Ibans and Bidayuhs) make up the majority in the state of Sarawak, while the Kadazan-Dusuns make up the majority in Sabah. In Labuan, the Bruneian Malays and Kedayans are the largest groups. Overall, the Malays are the majority in Malaysia and Brunei and form a significant minority in Indonesia, Southern Thailand, Myanmar, and Singapore. In Singapore, the demographics of the country is similar to that of its West Malaysian counterparts but instead of Malays, it is the Chinese that are the majority, while the Malays are the second largest group and Indians third largest.

Within the Philippines, the country has no majority ethnic groups; but the four largest ethnolinguistic groups in the country are the Visayans (mainly Cebuanos, Warays and Hiligaynons), Tagalogs, Ilocanos and Bicolanos. Besides the major four, there are also the Moro peoples of Mindanao, consisting of the Tausug, Maranao, Yakan and Maguindanao. Other regional groups in the country are the Kapampangans, Pangasinans, Surigaonons, Ifugao, Kalinga, Kamayo, Cuyonon and Ivatan.

In mainland Southeast Asia, the Burmese accounts for more than two-thirds of the population in Myanmar, but the country also has several regional ethnic groups which mainly live in states that are specifically formed for ethnic minorities. The major regional ethnic groups in Myanmar are the Tai-speaking Shan people, Karen people, Rakhine people, Chin people, Kayah people and Indo-Aryan-speaking Rohingya people living on the westernmost part of the country near the border with Bangladesh. In neighbouring Thailand, the Thais are the largest ethnic group in the country but is divided into several regional Tai groups such as Central Thais, Northern Thais or Lanna, Southern Thais or Pak Thai, and Northeastern Thai or Isan people (which is ethnically more closely related to Lao people than to Central Thais), each have their own unique dialects, history and culture. Besides the Thais, Thailand is also home to more than 70 ethnolinguistic groups of which the largest being Patani Malays, Northern Khmers, Karen, Hmongs and Chinese.

Cambodia is one of the most homogeneous countries in the area, with Khmers forming more than 90% of the population but the country also has a large number of ethnic Chams, Vietnamese and various inland tribes categorised under the term Khmer Loeu (Hill Khmers).
