This supplementary data set contains occupational classifications as well as a number of prestige or status variables that were not yet available on the first release of the main ALLBUS 2012 data set (ZA4614). In addition to this, the data set contains a number of identification variables and weights.

  1. Identification variables: Study number, respondent ID, German citizenship, region of interview.
  2. Occupation and prestige:
    • Respondent´s current occupation: ISCO 1988, SIOPS, ISEI (Ganzeboom), ISCO 2008
    • Respondent´s last occupation: ISCO 1988, SIOPS, ISEI (Ganzeboom), ISCO 2008
    • Current spouse: ISCO 1988, SIOPS, ISEI (Ganzeboom), ISCO 2008;
    • Current life partner: ISCO 1988, SIOPS, ISEI (Ganzeboom), ISCO 2008;
    • Father: ISCO 1988, SIOPS, ISEI (Ganzeboom), ISCO 2008;
    • Mother: ISCO 1988, SIOPS, ISEI (Ganzeboom), ISCO 2008;
    • Occupational metaclassification (Terwey): ISCO 1988, SIOPS, ISEI (Ganzeboom), ISCO 2008.
  3. Weights: transformation weight for analysis at household level, east-west weight for analyses of Germany as a whole.

Total Population and Sample:

  • Universe sampled: Federal Republic of Germany
  • Person sample: Two stage disproportionate random sample in western Germany (incl. West Berlin) and eastern Germany (incl. East Berlin) from all persons (German and non-German) who resided in private households and were born before 1 January 1994. In the first sample stage municipalities (Gemeinden) in western Germany and municipalities in eastern Germany were selected with a probability proportional to their number of adult residents; in the second sample stage individual persons were selected at random from the municipal registers of residents.
    Targeted individuals who did not have adequate knowledge of German to conduct the interview were treated as systematic unit non-responses.


Method of Data Collection:

  • personal interview with standardized questionnaire (CAPI – Computer Assisted Personal Interviewing)
  • two additional self-completion questionnaires (CASI – Computer Assisted Self-Interviewing) for ISSP (drop off; split questionnaire design)


 Primary Sampling Units / Sample-Points:



Sample-Points (in 103 municipalities)

The known literature using ALLBUS-Data is documented in the ALLBUS-Bibliography. This bibliography can be searched online on the ALLBUS microsite.


Further Notes:

  • Respondents from the area of the new federal states are oversampled.
  • Data set ZA4618 is a supplement to ALLBUS 2012 (ZA4614). Thus, ZA4618 is usually not analyzed as a stand-alone but in connection with data from the main data set ZA4614. In order to do this, the two data sets have to be merged. Key variable for merging the data sets is V2 IDENTIFIKATIONSNUMMER DES BEFRAGTEN (respondent ID).
