Although differences in social capital have been linked to a variety of outcomes, we know little about why it varies in the first place. Using experimental data from high schools in the north and south of Italy, this column argues that migration is one possible explanation. It finds that civic students in the south are more likely to emigrate when the local share of civic peers is either low or high compared to when it takes an intermediate value, while the opposite happens for uncivic students. Migration thus causes a ‘civicness drain’.
