Deux bases de données, aucune référence de prix. Comment observer les prix immobiliers en France avec Dvf et Perval ?

While they are sharing the same initial data source, the two main datasets on real estate prices in France (Dvf and Perval) differ substantially from one another. They are not designed to address similar issues and are therefore different in their structure and content. This means that, potentially at least, these differences may impact the usability and the conclusions that can be drawn from these databases. In this research note, we point out how the data generation processes make it necesseary to take precautions in using these data. To do this, we use Dvf and Perval datasets on the urban area of Avignon (France) for 2014, that comprise 64 municipalities and the selling of 4500 real estate properties.
