Our research focuses on the relationships between socio-economic status, vicinal social networks and urban violence. Specifically, we use data from a survey done between 2004 and 2006 in six Argentine cities to explore the relationships between housing levels, social networks and victimization. The survey results are compared to what was found in ethnographic research. We discover that diverse kinds of social networks produce differing effects over victimization rates. Social networks based on kinship and friendship, do not have an effect on them. Instead, local leadership does play a deterrent effect, while conflictive social networks promote victimization. In this way, the survey data partly confirms and partly redefines what was found in ethnographic research.
