In France, a banlieue is a suburb of a large city. Banlieues are divided into autonomous administrative entities and do not constitute part of the city proper. For instance, 80% of the inhabitants of the Paris area live outside the city of Paris. Like the city centre, suburbs may be rich, middle-class or poor—Versailles, Le Vésinet, Maisons-Laffitte and Neuilly-sur-Seine are affluent banlieues of Paris, while Clichy-sous-Bois, Bondy and Corbeil-Essonnes are poor ones. However, since the 1970s, the phrase les banlieues has been increasingly used in European French to describe suburban low-income housing projects (HLMs) in which mainly foreign immigrants and French of foreign descent reside, often in perceived poverty traps.
