Query: Gender bias in the Erasmus students network   The Erasmus Program (EuRopean community Action Scheme for the Mobility of
University Students), the most important student exchange program in the world,
financed by the European Union and started in 1987, is characterized by a
strong gender bias. Girls participate to the program more than boys. This work
quantifies the gender bias in the Erasmus program between 2008 and 2013, using
novel data at the university level. It describes the structure of the program
in great details, carrying out the analysis across fields of study, and
identifies key universities as senders and receivers. In addition, it tests the
difference in the degree distribution of the Erasmus network along time and
between genders, giving evidence of a greater density in the female Erasmus
network with respect to the one of the male Erasmus network.
