The sociology of globalisation, cosmopolitanism or, on a different scale, the sociology of Europe all emphasise mobility and the intricacy of vertical and horizontal social relations and networks. This chapter presents the analysis of the social networks, resources and social capital of the managers of the sample. A key trait of the chapter is the use of some methods based on the analysis of social networks for understanding the sociability sphere of respondents. In the chapter, friendship is analysed along three dimensions: homophily (the tendency of individuals with similar socio‐economic background to establish friendships between them); social closure (analysing to what extent networks of friends are interconnected); and the duration of the relation, frequency of contacts and the ‘spatial’ dimension (the different social circles where relations have been formed). Social networks and social capital analysis confirm the importance of kinship in the metropolitan area.
