"FReDA - The German Family Demography Panel Study" is a scientific study that focuses thematically on family life and intimate relationships in Germany. The study provides researchers with representative, reliable, high-quality data, thus enabling them to conduct up-to-date analyses of the German population and of families in Germany. FReDA integrates (a) the German Generations and Gender Survey Round II (GGS-II) sample (FReDA-GGS), which is comparable with the GGS-II samples of 19 other countries or territories; and (b) the pairfam sample (FReDA-pairfam), with its rich body of longitudinal information from up to 14 previous waves of data collection.

To recruit the FReDA panel, a probability-based sample of 108,256 anchor persons between the ages of 18 and 49 years was drawn from the population registers of German municipalities. The final sample comprised over 20,000 anchor respondents, who are now surveyed biannually about their life situations. As a dyadic multi-actor study, FReDA additionally collects data from around 8,000 partners of anchors.

The questions included in FReDA explore a variety of demographic, psychological and sociological facets of life in Germany. Particular attention is given to family planning and couple relationships. Depending on the respondent’s life situation, the parent–child relationship or the relationships between the generations are addressed. In addition, FReDA includes, for example, respondents’ life satisfaction, well-being, attitudes and values, as well as their understanding of roles and structural frameworks.
