The majority of studies about networks and space analyze cities of the Global North, and only some investigations explore the effects of urban segregation in network production. This paper addresses the issue using research results about 361 personal networks of poor individuals in two Brazilian metropolises - São Paulo and Salvador. Physical proximity is relatively unimportant for the middle classes, but is central for the urban poor. Both segregation and localism have negative impacts on the presence of more socially integrated networks. Some types of networks contribute to integrate poor individuals, but they tend to be rarer exactly among the poorer individuals, creating strong circularity in inequality reproduction. This article explores the correlates of networks' spatial dimensions - localism and the presence of neighbors.
