Land values data to the municipality by period

Description

Since 2019, the Directorate-General for Public Finance (DGFIP) has made available to the general public the dataset “Requests for Land Values” (DVF). These data allow us to know the real estate transactions that took place over the last five years in metropolitan territory and the DOM-TOM, 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+. This data is organised at the transaction, making it easier to use. However, their operation remains complex. Here we propose a version of the DVF+ data that aggregates information at the municipal level and manages upstream the complexity of the information by applying a number of filters. The objective is to propose stabilised and homogeneous data on clearly identified perimeters. The organisation of this information at the level of the municipality (commune 2020 and communal districts) aims 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 way within a workshop of the LIFTI (Laboratoire d’Initiatives Foncières et Territoriales Innovantes). This workshop, led 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 the methods of setting up indicators and the set of 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](s) * Communes with less than 5 mutations (over the year or over the period) are absent from the dataset; * For more information on the DVF source and best practices for this source, please refer to the Vademecum available at this link: (https://opendata.caissedesdepots.fr/assets/theme_image/LIFTI_Logo%202017.jpg)!(s)
