Variations in Homicide Rates in Brazil: An Explanation Centred on Criminal Group Conflicts

The paper proposes an explanation for the variations in homicide rates in Brazil in the past two decades. Based on the comparison of ethnographic experiences lived in the criminal universe of four capital cities (São Paulo, Porto Alegre, São Luís and Maceió), we propose two analytical strategies: 1) the breakdown of quantitative homicide rate data by victim profile, and 2) the construction of historical synopses of conflicts between factions at the local level. We demonstrate how homicide rates, in specific socio-demographic profiles, oscillate based on changes in conflicts between factions at the local level conflicts, and influence variations in the aggregate rates.
