In some countries (particularly in Latin America), indigenous peoples form a sizable component of the overall national population — in Bolivia, they account for an estimated 56–70% of the total nation, and at least half of the population in Guatemala and the Andean and Amazonian nations of Peru. In English, indigenous peoples are collectively referred to by different names that vary by region and include such ethnonyms as Native Americans, Amerindians, and American Indians. In Spanish or Portuguese speaking countries, one finds the use of terms such as índios, "pueblos ", "amerindios", "povos nativos", "povos indígenas", and, in Peru, "Comunidades Nativas" (Native Communities), particularly among Amazonian societies like the Urarina and Matsés. In Chile, there are indigenous peoples like the Mapuches in the Center-South and the Aymaras in the North; also the Rapa Nui indigenous to Easter Island are a Polynesian people.
