The Enquête Décennale Santé (2002–2003) is a large-scale health survey conducted by the French National Institute of Statistics and Economic Studies (INSEE), comprising of 16,848 households across metropolitan France, designed to assess health status and medical consumption. Households were recruited between September 2002 and October 2003 using a stratified sampling method based on national databases. Each household was followed up three times, with visits spaced approximately one month apart, and data collection organized into five seasonal waves to account for temporal variation in health behaviors and conditions. This survey forms part of the INSEE’s Décennale Santé (Ten-Year Health) series, a broader program of decennial cross-sectional health surveys conducted since 1960 to monitor population health trends over time.
