The ability of local territories to create and attract human capital is key in generating progress at the local level. However, skilled workers not only tend to stem from certain regions, but to be attracted to them. This study analyzes interregional migratory movements in Chile, identifying differentials in local economic development as a factor that promotes selective migration of workers. The results indicate that regions with high levels of relative development attract more qualified migrants and expel the less qualified, thus reinforcing the initial concentration of human capital.
