The DEAS makes possible a comprehensive description of life situations and life contexts of the German population aged over 40 (cross-sectional analysis), an analysis of social changes over the points in time since 1996 and an investigation of intra-individual development over three to twenty-one years (1996-2002-2008-2011-2014-2017).
Starting from 2008, the DEAS panel is conducted every three years. A new cross-sectional sample is drawn every six years (1996-2002-2008-2014). This approach enables the investigation of social change as well as individual development over an twenty-one year span.
In 2017 the sixth wave of data collection was taking place: between April and November about 6600 persons were re-interviewed.
Data of all waves are available for the scientific community. For further information please visit the pages of our Research Data Centre (FDZ-DZA).
The following samples are available from the survey waves conducted between 1996 and 2017:
