Every empirical study has its limitations. This chapter highlights the methodological constraints of the study, such as the conflation of age, life stage, and generation in the cross-sectional design, as well as potential sampling biases. The measurement accuracy of individual factors is also critically examined. Suggestions for future research are provided, for example, longitudinal studies and a more detailed assessment of life circumstances. Despite these limitations, the strengths of the study are emphasized, such as surveying only employed individuals and the innovative analytical approach.
