Station neighbourhood of Villejuif - Louis Aragon

Overlooking the Bièvre valley to the west and the Seine valley to the east, the neighbourhood is crossed from north to south by the RD7, the area's main road. Its proximity to Villejuif town centre, the recent establishment of a higher education centre specialising in digital technology, and the presence of two hospital groups contribute to its appeal and dynamism. The neighbourhood is notable for its social diversity, thanks in particular to the variety of housing available, 33% of which is social housing. The population has grown significantly, by 11% between 2010 and 2021, in line with the delivery of numerous new developments, particularly in the Aragon ZAC (joint development zone), but also through multiple operations in the wider area, including the Coteau sector and along the RD7, often on former suburban plots. New green public spaces in the heart of the station block will improve connections between the T7 tramway and metro lines 15 and 7. 

Launched in 2013, the Grand Paris Express station neighbourhood observatory is a partnership tool that brings together the Paris Urban Planning Agency (Apur), the Société des grands projets (SGP), the Regional and Interdepartmental Directorate for the Environment, Planning and Transport (DRIEAT) and the National Institute of Statistics and Economic Studies (INSEE), as well as the Établissement public foncier d'Île-de-France (EPFIF) and the Institut Paris Region (IPR). Its aim is to report on the urban and social transformations linked to the arrival of the metro at the level of station neighbourhoods, lines and the network.

Ten years after the first survey, a new phase of the observatory has begun. In keeping with the timetable for the start of operations, the new studies are based on the same perimeter around each station, with an 800-meter radius corresponding to the immediate area of influence covered in a 10-15 minute walk. They also include the main indicators for comparative analysis.

Seven themes provide a fine-grained overview of current and future urban changes - Living environment - Population and jobs - Housing supply and prices - Local life, uses and new centrality - Accessibility and mobility - Environment. They are accompanied by a simple datavisualization, accessible to all from the Apur website and updated every year.
