ABSTRACT
The object of the study was to be the 'middle classes' because as he said 'save in respect of their early history "the middle classes" of Britain have not been much exposed to investigation'. The method was modelled on demography and used statistical techniques, in particular the index of association, to measure intra-generational social mobility. Valuable information was provided about the extent of self-recruitment in the various social classes and in certain occupations that is medicine. American studies have also been influenced and have defined their conception of the problems of social mobility and methods of investigating it in a similar way. J. Goldthorpe and D. Lockwood argued that there was a process of class convergence taking place, characterised by 'instrumental collectivism', but they stressed that this was in no way to be confused with the process of assimilation of working people into middle class life.
