Unit definitions
Dwellings The dwelling may be made up of a room or a group of rooms, in which a person or a group of persons live together under the same roof if the dwelling satisfies the conditions of separateness and independence. Separateness is understood to be the fact that the building is surrounded by walls, partitions, or dividers that isolate it from other buildings. Independence means that the building has a direct entrance from the street or from a hallway, stairway, corridor, etc., that allows the occupants to enter and leave without passing through other dwellings.
Households A census household is a person or group of persons, related or unrelated, who live under the same roof and who share a common budget in order to satisfy their basic needs.
Collective dwellings Collective dwellings comprise those buildings that are structurally separate and independent, meant to provide shelter for large groups of persons. This includes hotels, hostels, guest houses where more than 5 persons are lodged, hospitals, welfare institutions, convents, boarding schools, worker's camps, barracks, etc.
