Who is studied
The survey is based on a representative sample of 5,002 individuals from the German-speaking residential population, aged between 55 and 70 years (birth cohorts 1942 to 1958). The study focuses on the life plans and potentials of older adults in the labor market, civil society, and family, as well as their transitions into retirement. In spring 2013, a 40-minute telephone interview was conducted using a standardized survey instrument. It included measures in the following areas: sociodemographics, employment and retirement transitions, informal work in civil society and family, perceptions of aging, health and well-being, and personality. In 2015/2016, participants from the first wave who were willing to be re-interviewed were surveyed again. In total, 2,501 interviews were completed at T2
