Child Type (CTPP)
This classification identifies children according to different types of parent-child relationships within families and is applicable to all children irrespective of their age, present in the household.
The classification includes categories for natural, step and foster children. Adopted children are categorised together with natural children. Any other person aged under 15 years is coded to 'otherwise related child (under 15)' or 'unrelated child (under 15)'. Boarders and lodgers aged 15 years and over are coded to 'not applicable'.
The categories 'step child' and 'foster child' are not necessarily pure counts as a parent may report such a child as being a child of Person 1 and Person 2. In this case the child would be classified as a 'natural child'.
A natural, adopted, foster, or otherwise related child may be in a one or two parent family. Cross classification with Family Composition (FMCF) allows analysis of different family types.
