A straightforward definition of a supplementary point or category is that this is a point with no weight or mass. Whereas a passive category belongs to an active variable, that is a variable where the other categories still are active, a supplementary point belongs to a variable where all the categories are supplementary. Fortunately, when doing an multiple correspondance analysis (MCAspe), the only major change for the researcher is to decide what categories to define as passive. In Distinction, Bourdieu's ambition was to analyse the dialectic between the structures in the social space, the structures in the field(s) and the structures in the agents' habituses. The inclusion of supplementary variables opens up the possibility of examining the cloud of individuals by including structuring factors in the analysis. Structuring factors are variables or descriptors that do not take part in the definition of the distances in the clouds.
