The word "banlieue" is, in formal use, a socially neutral term, designating the urbanized zone located around the city centre, comprising both sparsely and heavily populated areas. Therefore, in the Parisian metropolitan area, for example, the wealthy suburb of Neuilly-sur-Seine may be referred to as a "banlieue" as might the poor suburb of La Courneuve. To distinguish them, Parisians refer to a "banlieue aisée" (in English: comfortable suburb) for Neuilly, and to a "banlieue défavorisée" (in English: disadvantaged suburb) for Clichy-sous-Bois.
