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, further waves followed in 2002, 2008, and 2011. The surveys in 2002 and 2008 considered a cross-sectional sample as well as a panel sample of study participants who had entered the DEAS earlier.

Starting from 2008, the DEAS panel is conducted every three years. The most recent survey in 2011 therefore considered panel participants only. A new cross-sectional sample is drawn every six years. This approach enables the investigation of social change as well as individual development over a 15 year span.

Particular issues addressed in the surveys 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.
