Twenty-five years ago, Krivo and Peterson wrote a seminal piece on the context of disadvantage and its threshold effects. In The Structural Context of Homicide: Accounting for Racial Differences in the Process, they emphasize that extreme contexts of disadvantage may diminish the significance of certain structural conditions that contribute to higher crime rates, particularly in relation to homicide. However, remarkably few studies consider the threshold effects of disadvantage when studying homicide. Although their research primarily focuses on race groups and the varying degree of disadvantage as a crime-generating condition, the unequal distribution of disadvantage in communities may have unique effects on certain forms of violence, particularly gang homicide. This study will (1) explore how community predictors of gang homicide differ across contexts by comparing neighborhoods with extreme levels of disadvantage to those with low-moderate levels of disadvantage and (2) examine differences in this context of disadvantage between gang-related and nongang-related homicide to assess if differences emerge between these categorizations of lethal violence. Findings reaffirmed Krivo and Peterson’s conclusion. Disadvantage was associated with increases in gang homicide only in low to moderately disadvantaged areas while effects diminished in extremely disadvantaged communities.

The Americas have the highest regional homicide rate in the world, and high rates of homicidal violence related to organized crime. This research brief, excerpted from the UNODC Global Study on Homicide 2023, notes several recurrent patterns with respect to factors shaping criminal homicides in Latin America and the Caribbean: › Homicides related to organized crime and gangs are significantly more volatile than homicides perpetrated by intimate partners or other family members. › Subregions, countries and cities with a high homicide rate tend to be associated with a larger proportion of firearm-related homicide. › Settings with a high homicide rate also typically report a large proportion of homicides involving male victims. › High homicide rates are also usually associated with a proportionately higher number of homicides related to organized crime. Where there is a higher density of criminal organizations, there is a higher risk of homicidal violence. › Drug markets alone do not predict homicide but they are frequently associated with lethal violence, especially in the context of multiple competing criminal factions. Amid mounting public concern with violent crime and low trust in police, some Latin American and Caribbean governments are enacting “states of emergency” in response to organized crime and violent gangs. The United Nations High Commissioner for Human Rights has expressed concern about the human rights impacts of states of emergency introduced to address organized crime and violence1, while the Secretary-General’s New Agenda for Peace policy brief 2 notes that over-securitized responses can be counterproductive and can reinforce the very dynamics they seek to overcome, as their far-reaching consequences – blowback from local populations, human rights violations and abuses, exacerbation of gender inequalities and distortion of local economies – can be powerful drivers for recruitment into terrorist or armed groups.
