Research Data Centre (FDZ-DZA)

The German Ageing Survey (DEAS) is a longitudinal study on the living situation of individuals aged 40 and above in private households.

The study "Old Age in Germany" (D80+) is a cross-sectional survey on the living situation of individuals aged 80 and above in private households or care facilities.

With a slight delay but plenty of new features, data of  DEAS 2023 and DEAS 2021 Refresher surveys are now available! This new DEAS dataset  release also includes updates to all previous waves, as well as refreshed metadata and weighting datasets.

The data from DEAS and D80+ are available as Scientific Use Files (SUF) upon completion of a usage agreement.

Based on our data, hundreds of scientific publications have already been published - easy and convenient to research.

The German Survey on Volunteering (FWS) is only available at the GESIS Leibniz Institute for the Social Sciences.
