The title of this volume recalls that of Alain Touraine's book Le monde des femmes, and shares its main theses. It is argued, in fact, that in order to grasp the innovative and significant processes of change for the contemporary society, we must pay renewed attention to women as social subjects who act as a function of a "recomposition of the world". This thesis is put to the test on the empirical ground, with the results of some research carried out in the Prato "district", a rapidly changing society in which women emerge as the central subject of change - in the workplace, but also in the cultural and political sphere - presenting themselves as agents of social and economic transformation. The research field focuses on self-employed and entrepreneurial work, on private practices and, in relation to these, takes into consideration the family, the processes of formation of social capital, the generational turnover, including in the analysis also the migratory phenomenon. The publication of this work was encouraged and supported by the Soroptimist International Association of Prato and, in particular, by the President Anna Edy Pacini Sanesi.
