German Ageing Survey
The German Ageing Survey (DEAS) is a nationwide representative cross-sectional and longitudinal survey of the German population aged over 40.
The study focuses on two main perspectives:
- Actual life situation: How do people live in the second half of their lives and how greatly do the life situations of these people differ?
- Change in life situations: How have life situations in the second half of life changed over the period 1996-2008? In which areas of life has the situation improved and in which has it deteriorated, in which areas are the situations of individuals becoming similar and in which do differences between people increase?
DEAS microdata is available free of charge to scientific researchers for non-profitable purposes (www.dza.de/en/fdz/german-ageing-survey.html).
