Stage in life
The classification of stages in life is used to distinguish between the stages of a household-dwelling unit, which usually differ in terms of income and consumption. The classification is based on type of household-dwelling unit, age of reference person and age of children.
The household-dwelling unit's stage in life is described by the age of the reference person in cases where the household-dwelling unit does not comprise a family (single-person households, non-family households comprising at least two persons) or where the family consists of a married or cohabiting couple without children. The stage in life of a family with children is determined by the age of the children belonging to the household-dwelling unit. Since 1993 families consisting of a cohabiting couple with children have been classified separately from families consisting of a married couple with children.
