3. The households
The definition of Household adopted for this census is that of a domestic unit, formed by one person or a group of two or more persons, related or not, who live together in the same dwelling, share the same services, and maintain a common food budget. This constitutes the general framework within which persons will be identified.
The usual resident population, present or absent at the time of the census, is included in the Household (criteria for a de jure or "de derecho" census).
A household may occupy part or all of a dwelling, but it can also live in encampments, tenements, boarding houses, or refuges. They can also be the administrative, maintenance, or security personnel of an institution. They may also not have any place of abode.
In the presentation of the census results and according to size, households will be classified into:
One-person household: Household formed by one person who lives alone in all or part of the dwelling and does not share a food budget with anyone else.
Multi-person household: Household constituted by two or more persons. At the same time, multi-person households, according to the family relationship of the members to the head ("Jefe o Jefa") of household, are classified as:
Nuclear households: A concept restricted to family, limited to the closest family relationships. Four types of nuclear families can be conceived:
Married couple without children.
Married couple with one or more children.
Father with one or more children.
Mother with one or more children.
To form part of the nucleus, a child should be unmarried and not have a partner.
Nuclear families can also be classified according to the following types:
Primary: The family nucleus formed by the head of household, his/her spouse or partner, children, whether or not they are children of the partner with whom the head lives, legally adopted children, "hijos de crianza" [children being raised by the head who are not biological children] (if, in fact, recognized as such), and children from a previous marriage, only when they are recognized by the Head and are unmarried without children.
Secondary: Nuclear family formed by members of the household who do not belong to the primary family nucleus.
-- Extended households: Households formed by a nuclear Household and other persons related to the head of household; e.g. a mother or father with a child (or children) and another family member
[p. 23]
(or other family members) or a married couple with another family member (or other family members). A household made up by a group of relatives that does not correspond to the definition of nuclear household is also considered to be an extended household; e.g. two or more persons who are related to each other, but neither one constitutes a nuclear family.
-- Compound households: Those households formed by nuclear or extended households and other persons not related to the head of household. A group of unrelated persons living together also constitute a compound household; e.g. two or more nuclear families not related to each other, with or without another person; or two or more related persons not forming a nuclear household living with other unrelated persons.
