This article contributes to the analysis of the processes of student training mobility and anchorage in Brittany's university cities. Using a quantitative methodology, we have re-examined, on the one hand, the hypothesis that students have become more and more mobile, and we have also looked at their anchorage in the university city (both their residential and urban practices per se). Our reference population is that of IUT (technological university institute) students, at bachelor degree level (Ist, 2nd, and 3rd year) and Breton university MA students (1st and 2nd year).
