The main objective of WP1 is to shed light on the factors influencing young people’s (aged 14-35) wellbeing during the pandemic and beyond (in the short-term during the pandemic, and in the medium term until 2024). Next to examining, with a cohort approach, whether the wellbeing of the cohort experiencing the pandemic was differently affected compared to a pre-pandemic cohort, we also examine two types of factors contributing to this (1) whether the well-being effect of the pandemic was different depending on the socio-economic position of the young people and (2) whether the well-being effect was driven by changes in social connection, in socio-economic position and changes in school and work situation during the pandemic.
