Several studies highlight that the labour market entry is strongly influenced by informal relational networks (friendship and kinship). Given that informal networks have a relevant role in job position, the present work deals with the analysis of the relationship between social and occupational segregation in the labour market context. Starting from a panel survey on 506 unemployed people (and informal economy workers) enrolled in the database of the Labour Agency of Scampia in Naples, we define a network structure. In particular, the analysis of the affiliation matrix, where professional profiles related to undeclared works of officially unemployed people are the nodes and professional profiles of their three most important friends are the events, is performed to identify the underlying dimensions of the joint factorial map defined by both actors and events.
