In general, those Indigenous peoples within Canada who describe themselves as "First Nations" do not believe or hold with the concept of sovereignty of Indigenous peoples as nation-states, while those who do not use the term, or insist upon the term "Indigenous peoples" are sovereignists.
All members of First Nations who are entitled to benefits are entered in the Indian Register, which serves as the official record of members of First Nations.
