Census subdivision (CSD) is the general term for municipalities (as determined by provincial/territorial legislation) or areas treated as municipal equivalents for statistical purposes (e.g., Indian reserves, Indian settlements and unorganized territories). Municipal status is defined by laws in effect in each province and territory in Canada.

Census subdivision type

Census subdivisions (CSDs) are classified into 53 types according to official designations adopted by provincial/territorial or federal authorities. Two exceptions are 'subdivision of unorganized' (SNO) in Newfoundland and Labrador, and 'subdivision of county municipality' (SC) in Nova Scotia, which are geographic areas created as equivalents for municipalities by Statistics Canada, in cooperation with those provinces, for the purpose of disseminating statistical data.

The census subdivision type accompanies the census subdivision name in order to distinguish CSDs from each other, for example, Balmoral, VL (for the village of Balmoral) and Balmoral, P (for the parish / paroisse (municipalité de) of Balmoral).
