====Household Composition==
----
The number of people living in the household has been recorded at each wave of the study, from when the study member was a child (birth to 15 years) to when they were an adult (26 to 68-70 years). The categorisation of the ages of the household occupants varies between collection waves.
In their childhood, information was recorded on the number of parents and their children living in the house (including their sex and ages) and the number of other people living in the house (including relationship, sex and age). In [[questionnaires:1972|1972]], [[questionnaires:1982|1982]] and [[questionnaires:1999|1999]] a full household grid with relationships (and in [[questionnaires:1982|1982]] employment status) was recorded, but in [[questionnaires:1999|1999]] the information was grouped into the total number in the household, the number of children under 16 and the number aged 16 and over. \\ In [[questionnaires:2009|2006-10]] and [[questionnaires:2015|2014-16]], the study members were asked, how many people lived in their household, including themselves.
A measure of crowding has been created by dividing the number of people living in the household by the number of rooms in the house (for most waves from birth to 26 years). Two further derived measures exist for childhood which illustrate when, if at all, the child grew up in crowded conditions.
