Data was collected in 2007 and had a sample size of 60,809 individuals.


Disproportional stratified random sample, stratified by insurance provider, sex, nationality and cohort.

Data from three data sets: Versicherungskontenstichprobe (DRV-Bund), Integrierte Erwerbsbiografien (IEB) (Bundesagentur für Arbeit), Betriebs-Historik-Panel (BHP) (Bundesagentur für Arbeit), Germans belonging to the cohorts 1940 to 1977 with residence in Germany.

Sample: 30 to 67 years, Persons with a valid contributions account with the German Pensions Insurance as at 31.12.2007

Representative for persons with a valid contributions account with the German Pensions Insurance as at 31.12.2007

The data set connects longitudinal information from the pension insurance accounts with biographical data from the Federal Employment Agency (BA). Information by the Sample of Pension Insurance Accounts includes employment, unemployment, education, military/civil service, periods of sickness, child-raising periods, self-employment subject to social insurance, non-professional long-term caring (since 1995), minor employment (since 1999), pension and place of residence. Information by the data sets of the Federal Employment Agency (BA) includes profession, actual job, receipt of unemployment benefits, times of job seeking, measures during job seeking, information on the enterprise, places of residence and occupation, occupational status and working time.

The Research Data Centre of the Federal Employment Agency in the Institute for Employment Research (FDZ BA/IAB) and the Research Data Centre of the German Pension Insurance (FDZ-RV) offer longitudinal individual-level data sets. These data sets contain, on the one hand, information on the social security notifications and, on the other hand, characteristics of the administrative procedures of both institutions. In each institution, only information about the accomplishment of their own current tasks is recorded. The ambition of this project is to compile a common data set which contains data of the RV and the BA, respectively the IAB. The richness of information on individuals will be increased through filling up gaps in the single data sources with information of the other data source. This will provide new opportunities for scientific research. The combination of different data sources also supports the improvement of the quality of administrative records. (Source:
) The sample is very large and data have a high validity and correctness. It is possible to carry out differentiated analyses in small groups. Data comprise a large time frame – the whole insurance biography. There are no non-responses or memory failures. A comprehensive catalogue of items on the employment biography is recorded. The sample is very complex, descriptive results have to be analysed with sample weights. Only biographical information that is connected to pension insurance is recorded. Information on civil servants, occupationally insured (berufsständisch Versicherte) and foreigners without permanent residence status are missing. Information on (married) couples and households are also missing. There are no data on men and their children.
