Malaysian citizens are divided along local ethnic lines, with 69.7 per cent considered ''bumiputera''. The largest group of bumiputera are Malays, who are defined in the constitution as Muslims who practice Malay customs and culture. They play a dominant role politically. Bumiputera status is also accorded to the non-Malay indigenous groups of Sabah and Sarawak: which includes Dayaks (Iban, Bidayuh, Orang Ulu), Kadazan-Dusun, Melanau, Bajau and others. Non-Malay bumiputeras make up more than half of Sarawak's population and over two thirds of Sabah's population. There are also indigenous or aboriginal groups in much smaller numbers on the peninsular, where they are collectively known as the Orang Asli. Laws over who gets bumiputera status vary between states.
