The German Ageing Survey (DEAS) is a nationally representative study of individuals in private households aged 40 and over, which has been conducted repeatedly since 1996.
The German Ageing Survey
The German Ageing Survey (DEAS) is a long-term study conducted by the German Centre of Gerontology (DZA) and funded by the Federal Ministry for Family Affairs, Senior Citizens, Women and Youth (BMFSFJ). Since 1996, the study has tracked changes in life situations and ageing trajectories of individuals aged 40 and older through nationally representative cross-sectional and longitudinal surveys with several thousand participants.
Over the years, DEAS has continuously expanded: Following the first wave in 1996, further surveys were conducted in 2002, 2008, 2011, 2014, and 2017. Additionally, a short survey in summer 2020, a panel wave in 2020/2021, and a refreshment sample wave in 2021 were carried out. The most recent regular survey took place in 2023.
