Since 2005, the European Statistics Code of Practice has been the benchmark for assessing the quality of the output of national statistical institutes. Periodic reviews by European peers are organised to ensure that the principles of this reference framework are implemented and to ensure that each institute is committed to continuous improvement. Within this framework, INSEE has adopted a process-based approach. A range of tools, pooled within the Official Statistical Service (SSP), has been created to describe statistical production processes, analyse their strengths and weaknesses, assess the risks involved, examine their documentation (metadata) or assess a particular stage (analysis of users' needs, data validation, etc.). The diagnoses resulting from these « quality approaches » lead to the establishment of action plans that are regularly monitored in the context of « process reviews » . In addition, INSEE regularly conducts satisfaction surveys on the indicators and data it produces. The results of these surveys are available on the insee.fr website.

In addition, with regard to surveys carried out by services producing official statistics (INSEE, ministerial statistical services, other related bodies such as INED, Céreq, Inserm, etc.), the Label Committee is responsible for examining, on behalf of the National Council for Statistical Information (CNIS), all projects for which the approval provided for in Article 2 of the Law of 7 June 1951 is requested. Over time, the Committee has developed a method and a body of case law for examining the files submitted to it. Starting from considerations expressed in terms of the burden or proportionality of the collection to the objectives pursued, the Committee has extended its examination rules to cover all dimensions of statistical quality, as formalised in the European Statistics Code of Practice. For the SSP, the Label Committee thus constitutes a lever for ensuring compliance with these principles, whether in terms of consultation, methodological quality, proportionate burden, dissemination or availability of duly documented statistical sources.

On a more strategic level, the INSEE Inspectorate General carries out evaluations, assessments and audits of the Institute's work, its operations and the organisation of its services. Some of these missions focus more specifically on INSEE's key processes.

The « Trajectories and Origins 2 » survey was examined by the Official Statistics Label Committee and obtained the label of general interest and compulsory statistical quality.
