Context:
Indigenous peoples in what is now the contiguous United States, including their descendants, are commonly called "American Indians", or simply "Indians" domestically, or "Native Americans" by the USCB. In Alaska, indigenous peoples belong to 11 cultures with 11 languages. These include the St. Lawrence Island Yupik, Iñupiat, Athabaskan, Yup'ik, Cup'ik, Unangax, Alutiiq, Eyak, Haida, Tsimshian, and Tlingit, who are collectively called Alaska Natives. Indigenous Polynesian peoples, which include Marshallese, Samoan, Tahitian, and Tongan, are politically considered Pacific Islands American but are geographically and culturally distinct from indigenous peoples of the Americas.
