The population of these lands was sparse and semi-nomadic, with people living in tents or caves and surviving by hunting caribou and other large animals and by following this game as it migrated. The people living in the Subarctic can be broadly divided into two distinct ethnic groups with Athabaskan speakers in the east, including the Tsattine and the Gwich’in, and Algonquian speakers in the west, including the Cree and the Naskapi.
