France has long recognized the challenges faced by its vulnerable urban areas and has taken proactive measures to ensure housing affordability while addressing the social issues in its most deprived neighborhoods. To effectively implement these measures, access to reliable information is crucial. This need led to the creation of the “SIG de la politique de la ville.”

The “SIG de la politique de la ville” is an online atlas that compiles statistical and policy information about the “quartiers prioritaires de la politique de la ville” (Priority Zones for City Policies). These are areas identified for active urban regeneration policies.

Before 2014, two distinct urban policy priority areas coexisted: the regulatory area, which generated tax benefits (known as the ZUS area), and the contractual area, which generated funding (or “Cucs” area). These intervention methods did not necessarily overlap. The law on programming for cities and urban cohesion, enacted on February 21, 2014, reformed the geographic prioritization of urban policy. Using income as the sole criterion, new priority neighborhoods were identified in mainland France, La Réunion, and Martinique through a detailed territorial grid. This method was adapted for the overseas territories and revised in 2024.

As a result, 200 priority neighborhoods were identified by the decree of March 27, 2015, focusing on areas with significant urban dysfunctions, which became priorities for the new national urban renewal program. In 2024, a new delimitation process is underway.

The SIG system monitors the implementation of renewal programs and tracks the evolution of statistical data in these neighborhoods. On the website, users can select an address or region to see the priority neighborhoods within that area. By selecting these neighborhoods, users can access 1) basic statistical information on urban deprivation, 2) details of implemented plans, and 3) the progress of these plans.

This SIG tool is among the most advanced systems globally for tracking neighborhood affordability and deprivation.
