Social Class
Father’s and grandfathers’ occupation and childhood social class
Information about the occupation of the father was asked at many of the follow-ups in childhood. Occupation was initially coded according using the Registrar General's occupational classification at the time.
Derived commonly used variables: In 1976, the research team retrospectively applied the 1970 OPCS Classification of Occupations to code the current or last occupation and employment status of the fathers (or of the current husband) and derived the socioeconomic group and social class for the following years:
-
1950 (when survey members were aged 4 years)
-
1957 (when survey members were aged 11 years)
-
1961 (when survey members were aged 15 years)
In addition, the occupation, employment status, socioeconomic group and social class of the maternal grandfather and paternal grandfather were reported by the mother in 1954.
Study member and partner’s occupations and social class
Information about own and partner’s occupation asked at 26, 31, 36, 43 and 53 years.
-
Current own social class (at 26,36,43, 53 years)
-
Current or most recent own social class (at 26,36,43 and 53 years)
-
Current spouse social class (at 26,36,43 and 53 years)
-
Current or most recent own social class of spouse (at 36,43 and 53 years - not available at 26 years)
Head of household’s social class (based on own social class if male or unmarried female, and spouse social class if married female) was derived.
An overall measure of adult own social class takes current or last social class at 43 years and then, if not available, at 36 and then 26 years. A subsequent variables was derived at 53 years which takes current or last social class at 53 years, and imputes from earlier years if not available then. Similar variables have been created for measures of spousal social class
Attitudes to social class
Questionnaire E in 1972 (26 years) focused on study members' understanding of social class and social mobility.
