Postdoctoral Researcher (research line on Gender and Fertility)Postdoctoral Researcher (research line on Gender and Fertility)Temporary Contract. Postdoctoral ResearcherRef. R203/2026Project overviewThis project addresses one central research question: Is the intention to remain childless increasing across Europe, rather than individuals simply postponing parenthood?Using either longitudinal panel data or pseudo-panel data, the project will examine intentions to have or not have children and how individuals revise these intentions over the life course. Fertility intentions are not fixed preferences but adaptive plans formed under conditions of uncertainty. Individuals update their reproductive intentions as they encounter new constraints and opportunities throughout their lives. This perspective raises several additional research questions: At what ages do women and men shift from postponing parenthood to intending to remain childless? Once this transition occurs, are these intentions stable over time? And which factors are associated with the intention to remain childless across the life course?Main responsabilitiesConduct independent and collaborative researchon fertility intentions, reproductive trajectories, childlessness, and family formation from a life-course perspective.
