The term Southeast Asian Massif was proposed in 1997 by anthropologist Jean Michaud to discuss the human societies inhabiting the lands above approximately 300 metres (1,000 ft) in the southeastern portion of the Asian landmass, thus not merely in the uplands of conventional Mainland Southeast Asia. It concerns highlands overlapping parts of 10 countries: southwest China, Northeast India, eastern Bangladesh, and all the highlands of Myanmar (Burma), Thailand, Vietnam, Laos, Cambodia, Peninsular Malaysia, and Taiwan. The indigenous population encompassed within these limits numbers approximately 100 million, not counting migrants from surrounding lowland majority groups who came to settle in the highlands over the last few centuries.
