Traditional labour supply theories stress economic variables as unemployment and wages to explain differences inlabour supply behaviour. Nowadays a number of trends can be observed in the literature about labour supply theoryand modelling: the integration of market-based and power based perspectives; the realization that social andcultural 'non-economic' factors influence economic functioning and the increasing importance to space. In thispaper a concept will be presented, which contributes to the operationalization of these new perspectives in regionallabour supply modelling: the life-style concept.Life-style is the relative importance to different careers and can be considered as a latent variable. Life-style groupsare formed based on similar life-course patterns. These groups have different goals and choose a specificorganizational framework in line with these goals. Various back-ground characteristics of persons are assumed todetermine the life-style category someone belongs to.In this paper a review is made of the theory of the concept and its use in spatial research on the labour market. Thelife-style concept that will be used to model labour supply is specified and operationalized.
