Adult lifestage

Adult lifestage classifies adults in households aged 16 to 24 by the presence of dependent children in the household. Adults aged between 25 and 54 are classified by age, by the presence of dependent children in the household, and by the age of the youngest dependent child if any are present. Adults aged 55 and over are classified by age and whether they are in one- or two-person households. Those aged 55-74 are further classified by the presence of dependent children.
Adult lifestage uses the alternative definition of an adult - anyone aged 16 and over. This definition is different from the standard definition for adults, children and dependent children used in most census results.
