The DEAS is a nationwide representative survey of the German population aged 40 and older that combines cross-sectional and longitudinal samples. Participants from baseline samples (drawn every six years) are followed up and enter the different panel samples. Panel data was collected at the same time as baseline samples until 2008. Starting from 2011, panel samples are interviewed every three years. Thus, DEAS enables an analysis of social change using the cross-sectional data of 1996, 2002, 2008, and 2014, as well as an investigation of intra-individual development over three to eighteen years (1996-2002-2008-2011-2014).
