The federal government produces statistics that talk about status Indians, non-status Indians, Métis, Inuit, and that's the way it's divided. That's because in provinces, those aboriginals not on reserve are counted as part of the provincial total as opposed to aboriginal totals, unless they have two addresses, which many people do. Then you have to choose which address you want to use for them.
