The farther away from the Paris city centre, the more the "banlieues" of the south of Paris can be divided into two zones. On one side, there are the banks of the Seine, where working-class residents used to live (there are still pockets of disadvantaged areas) but also other areas that are especially well off. Also are large cities close to Paris, such as Chanteloup-les-Vignes, Sartrouville, Les Mureaux, Mantes-la-Jolie, Poissy, Achères, Limay, Trappes, Aubergenville, Évry-Courcouronnes, Grigny, Corbeil-Essonnes, Saint-Michel-sur-Orge, Brétigny-sur-Orge, Sainte-Geneviève-des-Bois and Fleury-Mérogis.
