Unit definitions |
Dwellings |
The dwelling is a separate and independent space located inside a multi-unit building, or defined as the building itself, which serves as a home. The building or the dwelling, as the basic element of the housing unit, is the appropriate frame of reference in which households and the members who make up those households are identified and then counted in order to ensure the exhaustiveness of the census. The comprehensive counting of buildings or dwellings is therefore the necessary first step to ensure the exhaustiveness of the census. |
Households |
An ordinary household is made up of a group of people, who may or may not be related to one another, who recognize the authority of the same individual, called the "head of household," who live under the same roof or in the same compound, and who pool all or some portion of their resources. The ordinary household is usually made up of the head of household, his or her spouse(s), and their unmarried children. In quite a few cases, the ordinary household may include the head of household’s married children, extended family (direct ascendants, descendants, and/or collateral relatives), and, in some cases, unrelated individuals. The fundamental criteria used to identify members of an ordinary household are as follows: (i) living under the same roof or in the same compound, (ii) recognizing the authority of the head of household, (iii) pooling resources, in whole or in part. It is important to note that a person who lives alone and provides for his or her own basic needs, i.e., food, clothing, housing, etc. constitutes a household. Likewise, a group of people (unmarried individuals, unrelated individuals, etc.) who share the same dwelling will be considered a household only if they recognize the authority of one of them, who is thus considered the head of household, and if they have arranged to take their meals together. If, on the contrary, these people maintain a certain mutual independence, aside from living together, then they do not form a household; there will be as many separate households as there are independent people. |
Collective dwellings |
A collective household is made up of a group of people who are not necessarily related to one another and who live together in the same institution for reasons of health, education, work, travel, discipline, or otherwise. It is the institution that regulates the conditions of their coexistence, taking its own objectives into account. This includes the following institutions: boarding schools and university residences; military boarding schools and barracks; solidarity housing projects (orphanages); hotels; prisons; temporary construction sites (construction camps); hospitals and other health facilities (psychiatric hospitals); convents and other religious institutions (monasteries). However, people who live freely and normally in these institutions with their entire family (wife or wives and children), form ordinary households. rdinary and collective households are a frame of reference in which individuals are identified and counted, as well as statistical units of analysis. |
