Unit Definitions (Census)
  1971 1982 2003
Dwellings See definition of household below. All rooms or all groups of rooms which, inside a larger construction, serve as a residence to a household or to one person living alone. If the building is entirely occupied by a single household or by one person living alone, this building is considered a residential unit or dwelling. ---  
Households A household is most commonly a group of persons living together who are generally, but not necessarily, related. They live in the same place and generally take their meals together. A person living alone comprises a household. To simplify the census count, the concept of household does not require that household members share either their meals or their budget. Instead, the basic criterion is whether or not they share a housing unit. Thus, the number of units will be the same as the number of households, except if some of the units are vacant. A group of people generally related by blood, but not required to be so, living in the same residential unit and usually taking their meals together. A person living alone makes up a household. A group of people living in the same dwelling, usually but not necessarily related by blood, who recognize the authority of a household head, and usuaally taking their meals together.  
Group quarters Persons living in institutions such as military barracks, hospitals, and boarding schools and cannot be directly connected to a head of household. Note that there may be private households living within the walls which contain institutional households, such as the household of a school or hospital director who occupies a separate housing unit in the school or hospital. Hotels, boarding homes, hospitals, barracks, etc The residence of individuals who live together in certain establishments, such as a hotel, boarding home, orphanage, or convent. These people live communally.
