Total population of them is 5 percent. In Sabah, they are categorized as their individual tribes. Furthermore, mot tribes fall under the term Kadazan . In Sarawak, the dominant tribal groups are Dayak, Iban and Bidayuh. While, in Peninsular Malaysia, they are called as "orang asli". 

As we know, their relationship with environment / rain forest is very tight and strong.
