Demographic development and structural changes in ageing result in complex questions. These frequently affect multiple academic disciplines. For this reason, we regard “age(FG ing)” as an interdisciplinary crosscutting topic. We use both quantitative and qualitative methods to facilitate appropriate investigation and discussion of the challenges that age-related demographic and structural change poses for society, individuals, and social work with different generations and the mastery of life situations in the course of life within the outline conditions of a social state. Against this backdrop, the department also views applied research, especially participation-oriented projects, as having the same societal importance and potential for knowledge as basic research.
