The aim of this chapter is to advance the theoretical reflection on mobile sociality by examining closely the main concepts arising from social theory that concur to define it. I start from the notion of spatial mobility, which represents a relevant element of society’s structures and in turn has the capacity to produce relevant social change, seen both as work mobility and mobility in the reproductive sphere. I analyse this notion, through and beyond Marxian categories, with the view of capturing their social meaning in terms of a critique informed by political economy. Then I turn to examining the classic sociological concept of social mobility, its recent vicissitudes, and why mobility has increased so much with modernity. After this, I address the concept of sociability and what makes it distinct from sociality. My analysis of sociality on the move addresses its structure that brings together 3 elements: communication, labour and mobility. Again here, I explore its social meaning as well as its main forms and the social dimensions embodied in them. Finally, I examine the concept of mobile sociality that includes these different notions, by reshaping and integrating them. My attempt is to reconstruct the shift from a debate considering mobility and sociality as two separate.
