  In the present article, we attempt to devise a typology of forms of part-time
employment by applying a widely used neuronal methodology called Kohonen maps.
Starting out with data that we describe using category-specific variables, we
show how it is possible to represent observations and the modalities of the
variables that define them simultaneously, on a single map. This allows us to
ascertain, and to try to describe, the main categories of part-time employment.
