Our empirical analysis utilizes nationwide Finnish register-based data on mental health, encompassing a spectrum of conditions from severe to less severe mental health problems. To identity causal effects, we employ a regression discontinuity design centered around the January 1 cutoff. We find that being born at the start of the year leads to better mental health outcomes. Notably, these effects, primarily influenced by relative school starting age, are driven by women in their late twenties.
