For each DEAS survey year, a number of documentation objects are available. We are working on expanding our range of documentation in English.

  • In the Survey Instruments, questionnaires resp. CAPI-templates in their original version are documented – for 2002 and 2008 in an English translation as well.
  • In the Short Descriptions (Kurzbeschreibungen) you will find detailled information on the sampling procedure, the classification scheme of the variable names and explanations for the user-friendly generated and constructed variables. The Short Descriptions are currently only in German.
  • Registered users may receive the SPSS-Syntax used to generate the constructed variables. Please contact the FDZ team.
  • In order to facilitate longitudinal and time-series analyses, the FDZ-DZA offers a Variable Correspondence List (with English and German variable labels). With this chart, it becomes obvious which information has been surveyed in which year and how the respective variable names are named.
  • In the Codebooks we compiled every variable of each survey year with their individual categories (including missing values), labels and overall frequencies.
  • The sampling procedure, the conducting of the survey and the data gathering for all DEAS waves to date have been executed by the infas Institut für angewandte Sozialwissenschaft (Bonn). For the survey years 2002, 2008 and 2011 the Methodological Reports (German only) are available.
  • For the supplemental data (regional context information, job demands), documentation is also provided (currently in German only).

 

If you use the content of these documentation objects for publications, we kindly request you to indicate the source according to the rules of good scientific work.

The online Statistical Information System GeroStat is open to the public and allows to conduct frequency analyses of numerous indicators from all DEAS base samples. Results can be differentiated by age-group, sex and region (East and West Germany) and show the weighted distributions of pivotal indicators from various life spheres of people in the second half of their life.


A detailled description of the data base and survey methodology of the DEAS can be found in the following publications (in German):
