Island Southeast Asia

Island Southeast Asia, which includes the Philippines, Malaysia, and Indonesia, is not just full of Austronesians aka Malayo-Polynesians aka Southern Mongoloids (undecided English terminology for this people) because there's been mixing with other races, like Arabs, South Asians, Spanish, Portuguese, Northern Mongoloids, etc.

The Southern Mongoloids have an admixture of the Australoid subspecies as an inherent characteristic of their race.

In Malaysia, Southern Mongoloids are simply called Malays, but in the Philippines, people do not use this term as they are perceived as the "default" race amongst others who are mostly mixed.  A theory as to why "Malay" is not used in the Philippines is that the word "mal" means bad in Spanish, and "mala" means bad luck in Spanish also.
