In Paris, most poor neighborhoods in the east have seen rising prices and the arrival of many wealthy residents. However, the process is mitigated by social housing and most cities tend to favor a "social mix"; that is, having both low and high-income residents in the same neighborhoods. But in practice, social housing does not cater to the poorest segment of the population; most residents of social dwellings are from the low-end of the middle class. As a result, a lot of poor people have been forced to go first to the close suburbs (1970 to 2000) and then more and more to remote "periurban areas" where public transport is almost nonexistent. The close suburbs (Saint-Ouen, Saint Denis, Aubervilliers, ...) are now in the early stages of gentrification although still poor. A lot of high-profile companies offering well-paid jobs have moved near Saint-Denis and new real-estate programs are underway to provide living areas close to the new jobs.
