 Due to the presence of higher education institutions (notably the University of Rouen and the NEOMA Business School) and the city's relatively small population, Mont-Saint-Aignan is considered the French city that has the largest proportion of students relative to its population (students represented in 2014 25,61% of the total population).The town is the fifth-largest suburb of the city of Rouen and lies directly adjacent to the north side of Rouen at the junction of the D 121 and D 43.In addition to its population of 21,265, there are also around 20,000 students at the University and the various "Grandes Écoles".
