"In his study Paris et l’agglomération parisienne (Bibliothèque de Sociologie Contemporaine, P.U.F., 1952) Chombart de Lauwe notes that “an urban neighborhood is determined not only by geographical and economic factors, but also by the image that its inhabitants and those of other neighborhoods have of it.” In the same work, in order to illustrate “the narrowness of the real Paris in which each individual lives . . . within a geographical area whose radius is extremely small,” he diagrams all the movements made in the space of one year by a student living in the 16th Arrondissement. Her itinerary forms a small triangle with no significant deviations, the three apexes of which are the School of Political Sciences, her residence and that of her piano teacher."
