Alaska Natives include three distinct cultural groups:Eskimo [or Inuit], Aleut, andIndian. Eskimo subdivisions include the Inupiat, Yu'pik, and Siberian Yu'pik [St Lawrence Islanders]. Thirty or more years ago, the term Eskimo was regularly utilized to describe Arctic peoples of all the Circumpolar North. Today, the more common usage in Canada and Greenland is Inuit. However, in Alaska, Eskimo is still actively used to distinguish this population from the Aleut and other Native groups such as Athasbascan-speaking Indians of central and northern Alaska; along with the Tlingit and other tribes from Alaska's Southeast.
