We determine the change in depression symptoms among children and adolescents during COVID-19 compared to pre-pandemic baselines. By using country differences in pandemic-related restrictions and school clo...

Following the onset of the COVID-19 pandemic, many countries faced short-term fertility declines in 2020–2021, a development which did not materialize in the majority of German-speaking and Nordic countries. However, more recent birth statistics show a steep fertility decline in 2022. We aim to provide empirical evidence on the unexpected birth dec...

Although abortion trends can be highly informative for understanding fertility reactions amid COVID-19 pandemic, this perspective is rarely taken yet. In contrast to many other countries, Germany has reached above-average fertility rates in the first years of the pandemic. However, in-depth subgroup analyses of these trends are lacking. This paper...

Much of the literature on fertility intentions has shown that they are broadly predictive of fertility behaviour. Fertility intentions tend to change over a person’s life. How religiosity affects these changes over time has rarely been the subject of investigation. In this paper, we focus on whether and how religiosity affects trajectories of lifet...

The expansion of public childcare and increases in female labor force participation (FLP) are major developments in European societies.
