Cet article fait partie de la revue Futuribles n° 253, mai 2000
At the end of the 1970s, a group of social scientists started a research project on the value Systems held by Europeans; using representative samples of the population of each country and basically identical questionnaires, they were then able to carry out three detailed studies, roughly ten years apart. A special issue of the journal Futuribles (number 200, July-August 1995) was devoted to the trends that emerged from the surveys held in Europe in 1981 and 1990. While awai-ting the publication of another special issue covering the whole of Europe on the basis of the results of the last survey, carried out in 1999 the main trends for France are briefly presented here for the first time.
