1. 'Relationship in household' underlies the suite of standards for Family statistics. It identifies and classifies the key relationships between persons usually resident in a given household. Although some collections output directly to the classification of 'Relationship in household', its major use is in providing the basis for derivation of 'Family composition', 'Income unit composition', 'Household composition' and 'Social marital status'. The 'Relationship in household' standard facilitates the definition, collection and classification of household relationship data in statistical collections.
2. It is important to note that the variable does not and can not identify all the relationships present in a given household. Primarily, the relationships classified by this variable are those between a particular individual called the reference person and each other member of the household. Persons other than the reference person may, in some collections, also identify a single closer relationship to one other member of the household, if such a relationship exists. The household reference person is thus used as the basis for the identification of income units and families and the classification of the household.
3. Terminology used in this standard is defined in the Glossary section of the 'Overview of family, household and income unit standards'.
