Land values data in the municipality by period

Since 2019, the Directorate-General for Public Finance (DGFIP) has made the dataset “Requests for Land Values” (DVF) available to the general public. These data allow us to know the real estate transactions that have taken place over the last five years in the metropolitan territory and the DOM-TOMs, with the exception of Alsace, Moselle and Mayotte. The data are derived from notarial deeds and cadastral information. CEREMA offers an open data, cleaned and structured version of the file, called DVF+. These data are organised at the transaction, which can make their operation complex. Here we offer a DVF database that aggregates information at the municipal level and manages the complexity of the information upstream by applying a number of filters. The objective is to provide stabilised and homogeneous data over clearly identified perimeters. The purpose of organising this information at municipal level (commune 2020 and municipal districts) is to make access to this information easier without losing its quality. The dataset is accompanied by a PJ document describing the method developed in a collegial manner within a Lifti workshop (Laboratory of Innovative Foncières and Territorial Initiatives). This workshop, facilitated by the CDC, allowed the creation of the dataset, with the help of the company Modaal which supported the script. This document is supplemented by a dictionary that explains how the indicators are compiled and all the filters applied to the data. In the dataset made available, the indicators are calculated as an annual average for two periods of 3 years, 2014 to 2016 and 2017 to 2019. * The DVF+ vintage mobilised is that of April 2022; [https://cerema.app.box.com/v/dvfplus-opendata](https://cerema.app.box.com/v/dvfplus-opendata “https://cerema.app.box.com/v/dvfplus-opendata”) * Municipalities with less than 5 transfers (in the year or during the period) are absent from the dataset; * For more information on the DVF source and best practices regarding this source, please refer to the Vademecum available at this link: <HTTPS://WWW.GROUPE-DVF.FR/CATEGORY/VADEMECUM/> (https://opendata.caissedesdepots.fr/assets/theme_image/LIFTI_Logo%202017.jpg)!(https://opendata.caissedesdepots.fr/assets/theme_image/MODAAL_V4-03.png)
