Derived variables: household composition

It is simple to ascertain at each Census the number of people in the same household as the LS member with their age, sex and other individual characteristics. However, relationships between household members are more difficult to study. From 1971 to 1991 the source of information on these was a question on relationship of each person to the head (or a joint head) of household. This left ambiguities in the relationships between certain household members - see the training module on households and families for more information. In 2001 a relationship grid was introduced for the first five people in the household but relationships may still be incomplete in larger households and some people found it too complicated to fill in accurately (an ONS presentation on households in 2001 assesses its accuracy).

Derived variables are provided by ONS (as described in the training module); the variables below provide further tools.
