This study, carried out in partnership with the Regional Department of Insee Ile-de-France, describes the 68 Grand Paris Express station neighbourhoods in regard to their employment-population balance. It also analyses their trajectory since 2010.

Among the 68 Grand Paris Express station neighbourhoods, 18 have predominantly “economic” characteristics with many more jobs than inhabitants, 26 are “residential” with a higher proportion of inhabitants and 24 are more or less “balanced”. The latter, closer to Paris, are also the most densely populated station neighbourhoods.
The nature of surface areas constructed between 2010 and 2021, was in tune with research to achieve a balance between jobs and residents in a great many neighbourhoods (29 out of 51 where there was significant construction). On the other hand, construction may have contributed to reinforcing the predominantly economic or residential characteristics of 22 other neighbourhoods.
Between now and 2030, the Grand Paris Express will considerably reduce the travelling time of all its station neighbourhoods, thus bringing residents closer to their workplace. The number of jobs accessible within a 45 minute journey, for station neighbourhood inhabitants, should see a 70% increase by 2030, once all the GPE lines are in service. The benefits will be even greater for neighbourhoods that are mainly residential (+105%).
