Child Type (including grandchildren) (CTGP)

This variable, like Child Type (CTPP), records the different parent-child relationships within families. However it differs from the standard CTPP variable in that it recognises grandparent-grandchild relationships as parent-child relationships, regardless of the age of the grandchild.

In the 2011 Census, data on the relationships people have with others in the same dwelling is mainly derived from question 5 on the Census Household Form, which asks for each person’s relationship to Person 1 on the form.

Grandparent families are recognised where there is a grandparent-grandchild relationship present and no parent-child relationship present in a family. Where a parent is temporarily absent from the family, and their relationship reported does not confirm their relationship to their child (for example, if person 1 is not a member of their family nucleus) that parent-child relationship cannot be coded. This can result in a small number of children being reported as grandchildren when a parent is simply absent on Census Night. Users should note that grandparent-grandchild relationships are constructed for the purposes of family coding in order to create a statistical family. It may not be representative of who provides care, for example a grandparent caring for their grandchild or vice versa. More information is available in the Grandparent families fact sheet.

For further information please refer to the data quality statements for Child Type (CTPP) and Relationship in Household (RLHP).

More information on Child Type (including grandchildren) (CTGP) is available in the 2011 Census Dictionary (cat. no. 2901.0)
