The Aurelia project is based on an international and multidisciplinary research consortium. In France, specialists in sociology, political science, geography, demography, law, public health, economics and medicine are organised in five teams: Ined, Lise-Cnam CNRS, EHESP and EHESS and Ires. The members of these different teams have already have successful scientific work achievements between them. The members of these teams are as well experienced in comparative analysis. The Aurelia consortium’s partner teams in Germany, Canada, Japan and the United Kingdom are leaders in their field and productive partnerships have as well already been tested by the consortium members.
