The concept of open data represents a massive evolution of recent years. In this context, access and use are free of rights for users without technical, legal or financial restrictions. It is part of a philosophy of open access to information. However, specific licenses govern the use of this type of data.
This type of data can be used, for instance, in analyses on individual files, contextual data, or for framing survey data.
The www.data.gouv.fr website lists the vast majority of open data available. The classification is carried out by theme, then a selection according to various criteria (spatial coverage, temporal coverage...).
Nevertheless, it may be useful to focus on a few themes by listing additional sites:
