THE CLASSIFICATION CRITERIA
22. Note that one-parent income units always include dependent children. In a one parent family with non-dependent children only, each individual comprises a separate one-person income unit.
THE STANDARD CLASSIFICATION AND CODE STRUCTURE
23. The standard classification of 'Income unit composition' is:
1 Couple only
2 Couple with dependent children
3 One parent
4 One person
Residual categories and codes
24. All income units are codable to one of the substantive categories of the classification from 'Relationship in household' data so there is no requirement for residual categories and codes.
25. A supplementary code of '0 Inadequately described' is provided for those cases where 'Relationship in household' data are insufficient to identify and classify the component Income units.
Definitions of the categories
26. The categories of the classification are defined as follows:
Couple only income unit: an income unit comprising two partners in a couple relationship.
Couple with dependent children income unit: an income unit comprising two partners in a couple relationship and all of their dependent children.
One parent income unit: an income unit comprising a lone parent and all of his or her dependent children.
One person income unit: an income unit comprising a person who is not party to either a couple or parent/dependent child relationship. Specifically this includes all persons identified by the 'Relationship in household' variable as non-dependent child, other related individual or non-family member.
SCOPE OF THE CLASSIFICATION
27. The classification applies to all income units.
28. 'Income unit composition' is coded from data obtained from 'Relationship in household'. The procedures for allocation of individuals to income units follow the same rules and procedures as the rules for identifying families explained in detail in the ABS Standard Variable 'Family composition', with the exception that persons not in couple income units or one parent income units are not allocated to any form of 'Other family' income unit. Such persons form one person income units. The procedures are as follows:
29. Where a couple relationship is identified, the couple will form the nucleus of an Income unit. If 'Relationship in household' data reveal the presence of one or more natural, adopted, step, or foster dependent children of that couple, the couple and the dependent children will be coded as a Couple with dependent children income unit. A couple without dependent children will be coded as a Couple only income unit.
30. Once any couple relationships have been identified in the household, if there is a lone parent with one or more natural, adopted, step, or foster dependent children, that parent and the children will be coded as a One parent income unit.
31. Any person in a household aged 15 or over who is not allocated to an income unit using these procedures will be coded as a One person income unit. Specifically, Non-dependent children of any age, Lone parents without dependent children, Other related individuals and Non-family persons in Family households; and all persons in Group households and Lone person households comprise One-person Income units.
32. Any Child under 15, who is not the natural, adopted, step or foster child of anyone in the household, is allocated to an income unit as a 'nominal child'. The ABS uses the concepts of the 'nominal child' and 'nominal parent' where to all intents and purposes a 'parent-child' relationship exists, to facilitate a more accurate and analytically useful picture of the arrangements that may exist in the household. Children under 15 who are not the natural, adopted, step or foster child of anyone in the household are allocated to an income unit in the same way as a 'nominal child' is allocated to a 'nominal parent' in family coding. See the ABS Standard Variable 'Family composition' for more detail. The rules for allocating a nominal child are applied in the following order:
33. Where an unattached Child under 15 is allocated to an income unit in accordance with the procedures detailed above, the child is treated in the same way as a natural, adopted, step or foster child. The income unit composition of the nominal parent's income unit is then established in accordance with the procedures set out above. This may result in a Couple only income unit becoming a Couple with dependent children income unit or a One person income unit becoming a One parent income unit.
34. In summary:
