While supportive social ties help to buffer against the consequences of poverty, few researchers have examined how people form such ties. New ties are often formed in routine organizations such as businesses, churches, and childcare centers, which, beyond being places to work, shop, or receive services, are institutionally governed spaces of social interaction. Based on the notion of organizational brokerage, we introduce a perspective that specifies when routine organizations contribute to tie formation and use it to reexamine data from existing qualitative studies of such organizations among the poor. We argue that successful brokerage will depend on the degree to which an organization’s institutional norms render interaction among participants frequent, long-lasting, focused on others, and centered on joint tasks; and that the ensuing networks may differ from other supportive ties in the sense of belonging they may cultivate, the form of generalized exchange they may engender, and the organizational connections they may create.
