Current times are characterized by unprecedented migration levels: millions of people are on the move worldwide. Thus, understanding why people decide to migrate is a major goal of policymakers and international organizations, and migration has become a prominent issue on the global research agenda. Traditional migration drivers can be divided into reasons to leave (‘push’ factors) and reasons to migrate (‘pull’ factors), and include income deprivation, dissatisfaction with public services and institutions in the home country, conflict and war, climate change, and social networks abroad. In this paper, we focus our attention on children’s well-being as a potential migration driver. We investigate it by using the Gallup World Poll, a repeated cross-section dataset of a survey conducted in more than 150 countries from 2006 to 2016. We estimate the association between planned and intended migration and children’s perceived well-being using logit models with standardized coefficients, robust standard errors, and year and country fixed effects. Estimates reveal a positive and statistically significant association between child-related concerns, migration intent and plans. In particular, the probability of individuals having migration intent and plans increases where they report lower levels of satisfaction with child-related issues, as measured by the Youth Development Index, an index driven by indicators of respect for children and satisfaction with the education system. Moreover, children’s well-being affects more individuals living in households with children than those without. Finally, migration is a child- and youth-related phenomenon: young individuals would like to migrate, and plan to do so, more than older individuals.
