Four separate research teams are working on the TRA-survey; each studying distinct parts of the sample and different topics. The so-called "demography" part is being studied by two research groups, one at INED (family and social mobility), and the other at INRA (occupational categories). The inheritance part is being explored by a PSE-INRA-INED joint team. And finally, a more detailed sample has been developed for one prefecture (or département, a county-size French administrative unit), the Loire-Atlantique, and is being developed and studied by two CNRS researchers.
