Funding, history and structure of the study The German Ageing Survey (DEAS) is funded by the Federal Ministry for Family Affairs, Senior Citizens, Women and Youth (BMFSFJ). The first survey wave was conducted in 1996. It was designed and carried out by the research group on ageing and the life course from the Freie Universität Berlin, the research group on psychogerontology of the University of Nijmegen and infas Institute for Applied Social Sciences, Bonn. From 2000 onwards, the German Centre of Gerontology (DZA) was responsible for the implementation and further development of the project. The second survey wave of DEAS followed in 2002, the third was conducted in 2008, the fourth was conducted in 2011 and the fifth was conducted in 2014. The data assessments are furthermore carried out by infas Institute for Applied Social Sciences. 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 18-year span. A book containing the key findings of the fifth wave will be published in 2016.Mahne, K., Wolff, J.K., Simonson, J., & Tesch-Römer, C. (ed.) ( 2016, in press ): Altern im Wandel. Zwei Jahrzehnte Deutscher Alterssurvey (DEAS). Wiesbaden: Springer VS. Various other papers will be published in scientific journals.DEAS publications Sampling The German Ageing Survey enables analyses of cohort differences, i.e. a comparison of individuals of the same age at different points in time and thus an examination of social change. Moreover, it allows longitudinal analyses, i.e. the comparison of information at certain points in time and hence a study of individual developments over time. The DEAS makes possible a comprehensive description of life situations and life contexts of the German population aged over 40 in the year 2014 (current cross-sectional analysis), an analysis of social changes over the points in time 1996, 2002, 2008 and 2014 and an investigation of intra-individual development over either six, twelve, fifteen  years or eighteen years (1996-2002, 1996-2002-2008, 1996-2002-2008-2011 or 1996-2002-2008-2011-2014  ). Another perspective results from the comparison of individual development over a six-year period in the three time-frames 1996 to 2002, 2002 to 2008 or 2008 to 2014, i.e. a comparison between the development of two or three birth cohorts in a specific age segment. Wave I Base Sample 1996 (B-1996): disproportionably stratified population register sampling according to age (40-54, 55-69, 70–85 years old) sex and geographical location (East/West) of the German population living in private households in the birth cohorts 1911-1956 (n=4.838) Wave III Panel Sample 1996-2002-2008 (P-1996-2002-2008); participants from B-1996 were interviewed for a third time (n= 994 ) Panel Sample (P-2002-2008); participants from B-1996 were interviewed for a third time (n= 1001 ) Base Sample 2008 (B-2008); Furthermore, a new cross-sectional sample of 40- to 85-year-old persons (n=6205) (birth cohorts 1923-1968) Wave IV Starting from 2008, the DEAS panel is conducted every three years. Therefore, the most recent survey considered panel participants only. All of these 4855 respondents have already taken part in at least one earlier wave. 1040 panel participants entered the DEAS in 1996, 957 persons were recruited in 2002, and the majority of 2858 participants were interviewed for the first time in 2008. Wave V Panel Sample 1996-2002-2008-2011-2014 (P-1996-2002-2008-2011-2014); participants from B-1996 were interviewed for a fifth time (n= approx. 888 ) Panel Sample 2002-2088-2011-2014 (P-2002-2008-2011-2014); participants from B-2002 were interviewed for a fourth time (n= approx. 866) Panel Sample 2008-2011-2014 (P-2008-2011-2014); participants from B-2008 were interviewed for a third time (n= approx. 2569) Base Sample 2014 (B-2014); a new cross-sectional sample of 40 - 85 year old persons (n= approx. 6003 ) (birth cohorts 1929-1974) The sixth wave will be conducted in 2017.
