Family structure of economic family was approved as a departmental standard on October 22, 2007.
Family structure refers to the combination of relatives that comprise a family. Classification on this variable considers the presence or absence of: legally married spouses or common law partners; children; and, in the case of economic families, other relatives.
Economic family refers to a group of two or more persons who live in the same dwelling and are related to each other by blood, marriage, common-law or adoption. A couple may be of opposite or same sex. Foster children are included.
By definition, all persons who are members of a census family are also members of an economic family. Examples of the broader concept of economic family include the following: two co-resident census families who are related to one another are considered one economic family; co-resident siblings who are not members of a census family are considered as one economic family; and, nieces or nephews living with aunts or uncles are considered one economic family.
Family structure of economic family is derived from the responses to questions about the relationships among the people who live in the household. To determine the structure of economic families, a family reference person must first be identified. The family is then classified according to the presence or absence of this reference person's spouse or partner, child(ren) or other relative(s). The economic family reference person is determined through procedures specific to the particular survey. Census families that contain a married or common-law couple (either with or without children) and economic families where the reference person has a legally married spouse or common-law partner in the family (regardless of whether or not the reference person also has children) are classified as couple families. Census families consisting of one parent with his or her child(ren) and economic families where the reference person has no spouse or partner but does have a child or children in the family are classified as lone-parent families. Economic families where the reference person does not have a spouse or partner, nor a child in the family, only other relatives, are classified as other economic families.
Family structure of economic family is incorporated within the classification of the previous standard, Economic family structure. The current standards take a more simplified approach, presenting each classification dimension as a separate concept. This approach provides greater conceptual and definitional clarity while simultaneously allowing users more flexibility in constructing whatever more complex, multidimensional classifications meet their needs for data presentation.
This standard presents a concept of the composition of economic family that differs from that presented in the United Nations' Principles and Recommendations for Population and Housing Censuses, Revision 2, 2007. The classification suggested by the UN for households containing more than one person and more than just the members of one family nucleus focuses on: whether or not there is a family nucleus; the number of such nuclei; and the relationship, if any, of other members of the household to the family nucleus or nuclei. This contrasts with the current standard which views the composition of the economic family in terms of whether the chosen reference person is a member of a census family and, if so, the composition of that census family.
The Conference of European Statisticians Recommendations for the 2010 Censuses of Population and Housing, 2006 recommends an approach similar to that of the UN.
