Unit definitions
Dwellings A dwelling is a place of abode for persons that is structurally separate and independent. There are two possibilities: (a) that it has been constructed, built, converted, or made available for shelter for people, only if it is not being used for entirely different purposes at the time of the census, and is occupied by persons the night before the Census Day in the case of an improvised or mobile shelter. The other possibility is (b) a building that is not meant for human habitation but is being used in that capacity at the time of the census.
Households A dwelling used, or meant to be used, as a separate and independent domicile or place of abode for one or more families or other group of persons, related or not, living together in a family-like system or a person who lives alone.
Collective dwellings A dwelling made up of a building or group of buildings used, or meant to be used, as a place of lodging for a group of people, usually not related, who live together for reasons of health, education, religion, discipline, work and others. Collective dwellings usually have common services for the occupants such as kitchen, toilets, bathrooms, and living rooms and bedrooms.
