  1. See Wasserman and Faust (1994) for the definition of the statistics used. M stands for male; F stands for female. Degree stands for Degree centralization (standardized); Closeness stands for Closeness centralization (standardized); Active connections includes student flows in different fields of study; the Assortativity score is [− 1,1]. Values in squared brackets refer to the entire network of Erasmus student flows and are taken from (De Benedictis and Leoni 2020)
