The Sample of Pension Insurance Accounts deals with pension entitlements of insured people. Detailed information on times relevant to pension insurance is available in the data set. The data set contains process-produced longitudinal data, so employment histories can be analysed without facing the usual problems of longitudinal surveys in social sciences – such as panel mortality or memory errors. The data set contains more validated information on details of the employment history than respondents normally remember. The sample is very large, so that detailed analyses are possible. The panel has been built since 1983, so it contains a great deal of information on social change. Information on topics other than occupation is mostly missing. There is only some information on education and qualification, but this is incomplete because these data are reported by employers voluntarily. Information on children born is only included for women, not for men. Households and couples cannot be identified. Data in this data set are selective – periods of employment as civil servants or independent entrepreneurs are not recorded. Data for employment periods in minor jobs are only recorded if they were registered by the minor employed. There is information missing on occupation periods of people who immigrated to Germany or who moved abroad from Germany. That means that nearly all people in Germany have a pension insurance account, but many of these contain large gaps without information on the occupation. Unclear accounts are the reason for another type of missing data. Data are not easy to handle as there is a lot of information in the data set that cannot be analysed and interpreted without knowledge of the German pension law.
