A pygmy is a member of an ethnic group whose average height is unusually short; anthropologists define pygmy as a member of any group where adult men are on average less than 150 cm (4 feet 11 inches) tall.[1] A member of a slightly taller group is termed "pygmoid".[2] The term is most associated with peoples of Central Africa, such as the Aka, Efé and Mbuti.[3] If the term pygmy is defined as a group's men having an average height below 1.55 meters (5 feet 1 inch), then there are also pygmies in Australia, Thailand, Malaysia, the Andaman Islands,[4] Indonesia, the Philippines, Papua New Guinea, Bolivia, and Brazil,[5] including some Negritos of Southeast Asia.[citation needed]
