The central question addressed in this article is how social ties within and outside the neighbourhood are articulated in different contexts for various population groups. Two major perspectives emerge from the literature on personal networks, neighbourhood effects, and neighbourhood-based social capital. The first assumes a compensation mechanism, whereby local and extra-local ties flourish at each other’s expense. The second considers that these two types of ties can be cumulated. After presenting the interpretations and empirical data that support these two perspectives and highlighting the persistent ambiguity on the issue, they are tested with the support of an original survey of 2572 people in 14 neighbourhoods in the Paris and Lyon metropolitan regions. A range of indicators for social ties is used to build two indices, one for local ties and one for extra-local ties. The article then examines variations between these indices as a function of individual characteristics and contexts to test whether compensation or cumulation exists between the local and extra-local ties. The main findings are, first, that local and extra-local ties each evolve along one dimension. In particular, working-class social ties do not appear to have a specific pattern. Second, compensation exists, but cumulation of local and extra-local ties is predominant. Lastly, this cumulation is a factor of inequalities. It benefits those with the most resources in terms of income, qualifications and occupation, as well as the residents of upper-class or gentrified neighbourhoods. Geographical origins also play a role for the descendants of immigrants, who establish fewer extra-local ties.
