map of annual income in the Paris metropolitan area, with red being more affluent and light yellow being the most impoverished.
the highest incomes are concentrated mostly in center city Paris and the arrondissements to the west, and the wealthier suburbs of Hauts-de-Seine. the working-class and gentrifying neighborhoods of eastern Paris such as Montmartre, Belleville, and Ménilmontant in the 18th, 19th, and 20th arrondissements are slightly less affluent than the rest of Paris, leading to the stark and pervasive poverty and marginalization of the banlieus of Seine-Saint-Denis in the northeast. the suburbs of Pantin, Aulnay-sous-Bois, and Clichy-sous-Bois remain highly isolated, derelict, and host some of the highest crime and murder rates in Western Europe. due to de facto racial and class segregation, much of the population in these towns are North African French along with African, Middle-Eastern, and South Asian immigrants - the residents of these banlieus recently rioted against police brutality and French racism in the autumn of 2005.
