Social inequalities: theories, concepts and problematics

This article aims to present a concise perusal of the different approaches developed in the study of social inequalities and in the relationships that they establish with manifold social processes and problems. The text does not intend to be exhaustive from the theoretical point of view, but rather to present an overview of the analytical complexity of the inequalities systems and demonstrate that they should be tackled in a multidimensional, systemic and multiscale perspective.
