"Rent map" - Announcement rent indicators by municipality in 2025

**Context of the project** Knowledge of the level of rents is important to ensure the proper functioning of the rental market and the conduct of national and local housing policies. In 2018, the Directorate-General for Development, Housing and Nature (DGALN) launched the ‘rent map’ project by joining forces with an economics research team from Agrosup Dijon and the Institut national de la recherche en agronomique (INRAE), and with SeLoger and leboncoin. In 2020, the project was taken over by the National Agency for Housing Information (ANIL), which published new versions of the map in 2022, 2023, 2024 and 2025. This innovative partnership made it possible to reconstitute a database with 9.1 million rental ads. On the basis of these data, the research team and ANIL have developed a methodology for estimating indicators, at municipal level, of rent (including charges) per m² for apartments and houses. These experimental indicators are put online in order to be usable by all: State services, local authorities, real estate professionals, private landlords and tenants. As of 2022, the maps are updated and published annually by ANIL. This project provides additional information to that offered by the Observatoires Locaux des Loyers (OLL), deployed since 2013 and reinforced since 2018 by the Elan law. Today, this associative network of around 30 OLLs publishes every year precise information on the rents charged in some 60 French agglomerations. **Presentation of the dataset** The data disseminated are indicators of advertisement rents, at the level of the municipality. The covered field is the whole of France, excluding Mayotte. The geography of the municipalities is that in force on 1 January 2025.\ Rent indicators are calculated using ad data published on the leboncoin and SeLoger Group platforms over the period 2019-2025.\ The rent indicators are provided including charges for standard properties rented empty and rented in the 3rd quarter of 2025 with the following reference characteristics: * For an apartment (all typologies combined): 52 m ² area and 22.2 m ² average area per room * For apartment type T1-T2: 37 m ² area and average area per 22.9 m ² room * For apartment type T3 and above: 72 m ² area and 21.3 m ² average area per room * For a house: 92 m ² area and 22.4 m ² average area per room **Conditions for the use of data** These indicators may be used freely, provided that the source is indicated in the following form: ANIL estimates, based on data from the SeLoger Group and leboncoin. **Precautions for employment** Rent indicators are calculated including charges, based on unfurnished ad data. The data were duplicated but could not be based on highly discriminating photos and features. The mesh method implies, for municipalities with no housing rented via an advertisement on at least one of the two platforms over the period under consideration, that the rent indicator is that estimated for a larger mesh comprising neighbouring municipalities with similar characteristics. Users are advised to consider with caution rent indicators in municipalities where the coefficient of determination (R2) is less than 0.5, the number of observations in the municipality is less than 30 or the prediction interval is very wide.\ Moreover, compared to the previous version of the indicators published in 2022 , in 2023 or 2024, this map allows to compare rents only in cases where the indicators are calculated at municipal level throughout the period studied.
