Hard core : social fluidity in England and France in the 1970s and 1980s
John H. GOLDTHORPE
A model of the « core », or generic, pattern of social fluidity within the class structures of industrial societies was earlier derived from data on intergenerational class mobility in England and France from the 1970s. Here, the model is applied to more recent mobility data for these two nations. The model proves capable of reproducing the new data in much the same way as the old-indicating little change over time in underlying fluidity, despite continuing structural transformation. These results provide a test of the validity of the model, and it is further suggested that they support the idea that such temporal stability in fluidity patterns reflects the same constraints as those that create a large measure of cross-national commonality.
