Since 2004, France's ANRU has invested over €45 billion demolishing, rebuilding and redesigning housing in hundreds of deprived neighbourhoods, while the state auditor documents housing shortfalls, cost overruns and only partial progress on social mix.
The Agence Nationale pour la Rénovation Urbaine (ANRU) leads France's "Politique de la Ville" strategy for so-called quartiers prioritaires — deprived neighbourhoods identified nationally for intervention. Its programmes fund demolition of obsolete social-housing blocks, construction of new mixed housing (often built off-site to promote social diversity), rehabilitation of retained buildings, redesign of public space, and new community facilities such as schools and sports halls. Financed contracts must include "clauses d'insertion", binding construction firms to reserve a share of worked hours for local jobseekers.
Under the first programme (PNRU, 2004–2021), France's Cour des Comptes audited the results: roughly €45–48 billion invested overall (about €11 billion of it ANRU grants), covering some 600 neighbourhoods in 382 communes, with about 150,000 housing units demolished and 125,000 rebuilt — average project duration 14 years. The successor programme (NPNRU, since 2014) targets 448 priority neighbourhoods with roughly 3 million residents; by end-2025 it had delivered about 69,000 renovated or newly built social housing units against roughly 46,000 demolished, with 81% of its budget financially committed.
The Cour des Comptes' 2020 audit found only half of its 2014 recommendations had been implemented, flagged a projected cash-flow deficit peaking near €1.5 billion between 2025 and 2033, and concluded that "social diversity has not been achieved in a satisfactory manner". An independent analysis by the Fondation iFRAP went further, arguing that measured poverty reductions in renovated neighbourhoods substantially reflect displacement — 44% of demolished units housed poor households, versus 23% of units left standing — rather than genuine improvement for the original residents.
