In the 1st quarter N+2 :

A production and research file (FPR) is available to ministerial statistical services and certain public bodies (via Insee Info Service, forms must be completed, the first request being subject to the Statistical Confidentiality Committee) and to researchers (via the Quételet Centre). For other institutions and/or for requests for access to more detailed data, the requested data are made available via the Centre d'accès sécurisé distant aux données (CASD) after approval by the Confidentiality Committee.

Individual files are made available to researchers via the Centre d'Accès Sécurisé aux Données (CASD), subject to the agreement of the Comité du secret statistique.

Production and Research Files (PRF) are available to researchers via the Quetelet Diffusion network. Intermediate categories of detailed files concerning household surveys, these FPRs respect statistical secrecy but offer a greater level of detail than the «  all public » files.

FPR files are also produced, under certain conditions, for organisations with a public service mission such as SSMs, international organisations and public services.
