The Health and Solidarity Ministerial Statistical Department is the Directorate for Research, Studies, Assessment, and Statistics (DREES) of the Ministry of Social affairs, health and women's rights. DREES covers the following areas: health, welfare, social protection, the family, and women's rights.

Main missions

Within its sphere of competence, DREES designs the statistical apparatus, ensures its consistency, and collects, processes, and disseminates statistics. In liaison with the Research Ministry, it steers research policy.

It takes part in statistical projects and the presentation of their results. DREES prepares summary studies (in particular, economic accounts) and conducts socio-demographic, economic, and financial studies and projections; it coordinates and oversees studies carried out under the Ministry's aegis. DREES helps to promote assessment work and analyzes the structural effects of social policies.

It takes part in the design, validation, and implementation of assessment methods. It disseminates and publishes material that it has prepared or coordinated.

Statistical production

DREES collects information from surveys on all healthcare and welfare facilities, including public hospitals, private hospitals, homes for the elderly, institutions for handicapped children and adults and persons in difficulty, and "mother and infant welfare centers" (Centres de Protection Maternelle and Infantile: CPMIs). It compiles an index of hospitalisation costs and set up reporting channels for sampled hospitals to report financial information such as overall allocations, budget, and administration accounts.

DREES conducts surveys of specific population categories such as users of healthcare and social services, and social-benefit recipients.

DREES prepares the satellite accounts of the health and social-protection sectors in collaboration with INSEE, the Directorate-General for Public Accounting, and the Directorate-General of the Treasury and Economic Policy at the Ministry of Economy and Finance. DREES also acts as the secretariat for the two commissions in charge of the health and social-protection sectors of the national accounts.

Studies and forecasting

DREES publishes an annual appendix to the draft budget for the social-security (i.e., social insurance) system. The report highlights the key developments and trends that characterize the changes in France's health status and social conditions.

DREES routinely prepares demographic projections of the healthcare professions. It develops microsimulation models to assess the impact of tax and social-policy measures on the income of population categories.

DRESS carries out studies on the economic aspects of healthcare and social protection (e.g., drugs), qualitative assessments of reforms implemented (health insurance; public health policy; solidarity programs to promote autonomy for the elderly and the disabled; pensions; law to combat exclusion, etc.), and international comparisons (poverty and social inequality in Europe, definition and coverage of disabilities and dependency, etc.).

These studies draw on sources provided by INSEE and DREES, but also by other partners producing administrative, epidemiological, and statistical data: national social-security funds, Institute for Research and Documentation in Health Economics (IRDES), National Institute of Demographic Studies (INED), National Institute of Health and Medical Research (INSERM), Health Watch Institute (InVS), Pharmaceuticals Agency, and Regional Health Observatories. DREES seeks to develop opportunities for sharing data among these partners.

The Research Mission promotes dialogue between government units in charge of social issues and the research community. It encourages teams from universities, the laboratories of the French National Center for Scientific Research (CNRS) and, more generally, research institutions, to engage in studies that will meet the emerging need for knowledge in the fields of social protection, health, welfare, and social integration.


The results produced are all posted on the SOeS website.

Databases are accessible online, allowing users to download customised tables. On demand data processing services can be ordered.

Statistical data dissemination is also relayed via a network of regional centres in the decentralised offices of the Ministry of Ecology, Sustainable Development and Energy.
