German Ageing Survey (DEAS)
The German Ageing Survey (DEAS) is a nationwide representative cross-sectional and longitudinal survey of the German population aged over 40. It is funded by the Federal Ministry for Family Affairs, Senior Citizens, Women and Youth (BMFSFJ). The comprehensive examination of people in mid- and older adulthood provides micro data for use both in social and behavioural scientific research and in reporting on social developments. The data thus provides a source of information for decision-makers, the general public and for scientific research. The first DEAS survey wave took place in 1996, the second wave followed in 2002. The third wave of DEAS was conducted in 2008. Once again, participants were questioned in detail on their living situation. Particular issues addressed in the survey included an assessment of occupational status or living conditions after retirement, social participation and leisure activities, information on their economic and housing situation, family ties and other social contacts, as well as issues regarding health, well-being and life-goals. The third wave differentiates between three subsamples: (1) Persons who took part in the survey 1996 and 2002, (2) persons assessed in 2002, and (3) a new group of around 6,200 participants included in the study for the first time. This approach enables the investigation of social change as well as intra-individual development over a 12 year span.
