The DEAS is a nationwide representative cross-sectional and longitudinal survey of the German population aged 40 and older. 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, 2011, and 2014. Currently, the sixth wave is conducted by the infas - Institut für angewandte Sozialwissenschaft GmbH (infas Institute for Applied Social Sciences). The surveys in 2002, 2008, and 2014 considered a cross-sectional sample as well as a panel sample of study participants who had entered the DEAS earlier.

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.

Data of all waves is available to the scientific community. For further information to the use of DEAS data, please visit the pages of our Research Data Centre (FDZ-DZA).
