SAMPLES

Twice a year, FReDA surveys people who live in Germany and were 18- to 49-years-old at the time of the first survey. We refer to these study participants as “anchor persons.” Together, the two surveys from the same year form a wave. Every three years, these survey data can be linked with data from other countries within the framework of the Generations and Gender Survey (GGS) programme in order to carry out international comparative analyses. For more details on this sample, see FReDA-GGS anchor persons.

In addition, the FReDA survey data are used to continue the pairfam study samples. The anchor persons of these studies are people who live in Germany and belong to one of four birth cohorts: They were born either from 1971-1973, 1981-1983, 1991-1993 or 2001-2003. You can find more information about this under FReDA-pairfam anchor persons.

Finally, we also ask the partners of all interviewed anchor persons to participate in their own interview as well. This interview is shorter than that of the anchor persons. The questions mainly reflect information that the anchor persons have also provided and make dyadic analyses possible. You can find out more details about these samples at partners and ex-partners.
