Residence on or off-reserve refers to whether the person's usual place of residence is in a census subdivision (CSD) that is defined as 'on reserve' or 'off reserve'.
Area of residence: On reserve' refers to the following geographic areas: Indian reserves and settlements (referred to as 'On reserve'), and all other areas (referred to as 'Off reserve'). These geographic areas can be used to show where people, primarily Registered Indians and First Nations people, reside.
'On reserve' includes six census subdivisions (CSDs) types legally affiliated with First Nations or Indian bands, i.e., Indian reserve (IRI), Indian settlement (S-É) (except for the five Yukon settlements of Champagne Landing 10, Klukshu, Two and One-Half Mile Village, Two Mile Village and Kloo Lake), Indian government district (IGD), terres réservées aux Cris (TC), terres réservées aux Naskapis (TK) and Nisga'a land (NL), as well as the northern village of Sandy Bay in Saskatchewan.
Off reserve includes all CSDs in Canada not defined as on reserve.
