Relationship between Household Members |
Note
| This classification, closely related to that used in General Household Survey published data, relates to size of h/hold, whether there is a married couple present, and whether there are dependent children. For this classification, married and cohabiting couples are treated as equivalent, and dependent children include those up to 18, if they are still in (non- advanced) full time education. The elderly are defined as those over pensionable age (60 for women and 65 for men). Couple and lone parent h/holds may contain other individuals who were not family members. |
