I want to know the answer to the following question:
Why were these neighborhoods created?
All the background I'm provided with is that "Other difficult areas are located in the Seine valley, in Évry et Corbeil-Essonnes (Essonne), in Mureaux, Mantes-la-Jolie (Yvelines), and scattered among social housing districts created by Delouvrier's 1961 "ville nouvelle" political initiative.". Is that enough to answer the question?
