Each year, Santé publique France produces thousands of health indicators based on more than 70 surveillance systems, covering 90 diseases and health determinants, available down to the intermunicipal level. This data, available as open data via Odissé, is an essential resource for informing public policy decisions and fostering the development of innovative health initiatives. To mark its 10th anniversary, Santé publique France is launching the Odissé Dataviz Challenge today, which aims to transform this data into practical, accessible, and useful tools for everyone.

Three challenges, two weeks of production

Experts from Santé publique France and the data field will be available during dedicated webinars to support the teams.

The challenge is open to everyone, regardless of age or background: it’s open to students, researchers, designers, data professionals, data journalists, healthcare professionals, or simply anyone passionate about data. Both individual and team applications are welcome.

Schedule and Fees

Four webinars are scheduled before and during the challenge:
