Derivation of data:
The construction of Terwey's metaclassification of occupations proceeds in the following steps:
1) All respondents who are employed full-time or part-time are classified according to their own current occupation.
2) All respondents who were formerly employed full-time or part-time are categorized according to their last occupational status.
3) Only those married women and men who themselves have never been employed before are classified according to their spouses' occupation. If the spouse is a pupil/student, a housewife/househusband or doing compulsory military/alternative community service, classification is based on the father's occupation. For former ALLBUS-surveys the spouse's last occupation was used for categorization if the spouse was retired, unemployed or out of work for other reasons. As this information is not available since ALLBUS 1994, these cases are coded as not classifiable.
4) In previous ALLBUS-surveys, respondents who were widowed, divorced or living in separation and who had never been employed themselves, were categorized according to their previous spouse's occupation. As this information is not available since ALLBUS 1994, these cases are coded as not classifiable.
5) All unmarried respondents who have never been employed themselves are categorized using their father's occupation.
6) Insofar as they cannot be considered full-time or part-time employed in the sense of this metaclassification, respondents in compulsory military or alternative community service and those in vocational training represent a general exception. For these and for all other respondents who have no identifiable main occupation, the nearest possible occupational position is used. Married respondents in this group are, for example, categorized according to their spouses' current occupation or, if this is impossible, according to their fathers' occupation.
If a missing value ('Refused', 'Don't know' or 'No answer') appears within an occupation code relevant for metaclassification or if, for any other reason, occupational information does not permit a metaclassification according to a main occupation, the case is also coded as not classifiable.

International Socio-Economic Index of Occupational Status (ISCO-68)
In contrast to social prestige scales based on subjective evaluations of the relative social esteem of occupations, this index of socio-economic status was constructed using empirical data on the level of education and income related to a given occupation. The index scores were calculated for occupations coded according to ISCO-68. Cases for which there was no valid ISCO-68 code, could not be assigned an ISEI score. These cases were coded as ‘not classifiable’ (code 0).

Note:
Metaclassification of Occupations
The metaclassification of occupations allows an indirect occupational classification, e.g. according to the profession or occupation of the respondent's spouse or father, for those respondents who do not participate in the labor force. Thus, the purpose of the metaclassification is to arrive at a description of the social circumstance and social positions of otherwise unclassifiable respondents by (indirectly) linking them to positions in the occupational system in a principled way. Pappi himself points out that there is probably more than one way of constructing a metaclassification of occupations (Pappi 1979: 297). As an alternative to Pappi's rather male-centered operationalization (e.g. married women are classified according to their husbands' occupation, comp. V854-V862), Michael Terwey has developed a modified metaclassification scheme that gives more weight to women's direct social position (V863-V882). This more recent classification thus takes into account that in contemporary society it is more and more the individual's personal circumstance rather than his or her family's social capital that determines social position.
