The article aims to present and assess educational migration as a driver of human capital redistribution across regions. The unique research on academic careers of 8.5 thousand secondary school-leavers in Lublin (Poland) allowed to gather microdata on the mobility of young people along with the school-leaving examination results being a proxy of human capital. The results indicate that the ratio of youth out-migration from their home region amounts to roughly 20%, which seems a low figure against comparative studies. However, the distribution of migration rate along with the logit regression proved high propensity of the most talented youth to move out. Hence, strong positive migration selectivity is regarded as an important driver of human capital redistribution across regions, which might negatively affect human capital accumulation in the sending area.
