Objective: to identify characteristics, magnitude and factors associated with homicide in Manaus-AM, Brazil.

Methods: cross-sectional study, with data from the Mortality Information System (SIM); homicide rates and odds ratio (OR) were estimated, comparing to other external causes, for 2014; logistic regression was used.

Results: of the 1,657 violent deaths, 913 were due to homicide; homicide rate was of 55.8/100 thousand inhabitants (95%CI 52.1;59.7); odds ratio was higher among males (OR 3.4; 95%CI 2.3;5.1) when compared with females; among single (OR 1.6; 95%CI 1.1;2.5) and widowed individuals (OR 4.1; 95%CI 1.1;15.6), when compared with married individuals; at night/early hours (OR 2.1; 95%CI 1.6;2.9) and in the afternoon (OR 1.7; 95%CI 1.2;2.4), when compared with the morning period; the probability was higher among individuals under 35 years, with less schooling.

Conclusion: homicide mortality in Manaus was high, especially among males and young individuals with less schooling.

The geographical concentration of criminal violence is closely associated with the social, demographic, and economic structural characteristics of neighborhoods. However, few studies have investigated homicide patterns and their relationships with neighborhoods in South Asian cities. In this study, the spatial and temporal patterns of homicide incidences in Karachi from 2009 to 2018 were analyzed using the local indicators of spatial association (LISA) method. Generalized linear modeling (GLM) and geographically weighted Poisson regression (GWPR) methods were implemented to examine the relationship between influential factors and the number of homicides during the 2009–2018 period. The results demonstrate that the homicide hotspot or clustered areas with high homicide counts expanded from 2009 to 2013 and decreased from 2013 to 2018. The number of homicides in the 2017–2018 period had a positive relationship with the percentage of the population speaking Balochi. The unplanned areas with low-density residential land use were associated with low homicide counts, and the areas patrolled by police forces had a significant negative relationship with the occurrence of homicide. The GWPR models effectively characterized the varying relationships between homicide and explanatory variables across the study area. The spatio-temporal analysis methods can be adapted to explore violent crime in other cities with a similar social context.

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.

  At least 117,492 people were murdered in Latin America and the Caribbean during 2023, putting the median homicide rate around 20 per 100,000 people. But homicide data in many countries is missing or unreliable, so the actual number is likely higher. Here, InSight Crime dives into our yearly round-up, analyzing the organized crime dynamics behind the violence in each country of the region.

Despite numerous attempts to decrease homicides in the Latin American region, high homicide levels have persisted. Examining four cities in Rio de Janeiro, the research reveals the intense geographic concentration of homicides in each city, but illustrates differences in the extent of homicide concentration when using a variety of crime concentration measures. Single events involving multiple homicides and a homicide near repeat pattern are observed, with almost all these incidents taking place in areas of homicide concentration. The findings suggest that programmes targeted to areas of homicide concentration, including interventions that suppress the likelihood of future incidents, could decrease homicides.

For years, Ecuador enjoyed a relative degree of peace, as its neighbors, Colombia and Peru, were wrangling with internal conflicts as chief protagonists in the international supply of cocaine. However, things have changed dramatically in recent times. On 9 January 2024, the recently elected president, Daniel Noboa, said that the country was in a state of ‘internal armed conflict’ against 22 criminal groups that he described as ‘narco-terrorists’.

One of the most visible incidents of Ecuador’s growing problem with violence occurred in August 2023 when presidential candidate Fernando Villavicencio was assassinated at a campaign rally in Quito just weeks before the elections. Since Villavicencio’s murder, several incidents have occurred, including the arrest of the Colombian hitmen involved in his death and their subsequent murders in a prison, which has deprived the authorities of crucial evidence in the investigation.6 The year 2023 ended as the most violent recorded in the history of Ecuador.

The situation in Ecuador is complex, and more research into the political-economic factors behind how this once stable country descended into violent, crime-driven chaos needs to be undertaken if we are to fully comprehend the situation. Nevertheless, there are some key features of Ecuador’s criminal landscape that we do understand, and which can at least partly explain how the country has arrived at this critical juncture.

The existence of at least three intertwined criminal markets, the presence of transnational organized crime groups as well as local criminal networks, and the country’s poor resilience capacity to respond to and mitigate the effects of organized crime are all pivotal to understanding the complex criminal ecosystem that has emerged in force in recent years. In the last edition of the Global Organized Crime Index, published in September 2023, scores for Ecuador’s criminal markets and criminal actors are revealed.

This analysis provides but an initial understanding of the background. A more comprehensive assessment of how intersecting criminal markets, like arms trafficking and extortion, operate in the country will be essential in formulating sustainable, practicable responses to the crisis.

Preventing and reducing homicide means sparing hundreds of thousands of lives lost to violence every year. To do that, we must understand the complex and highly diverse range of threats and phenomena that drive and intersect with such lethal violence – from interpersonal dynamics to organized crime and rule of law to climate change, poverty and inequality to demographics, and much more – and how they differ across national and regional contexts. This Global Study on Homicide is an effort to reveal and delve into the facts behind the violence, to try and identify notable trends and to inform policies and solutions. The Study shows that 2021 was an exceptionally lethal year, with an estimated 458,000 intentional homicides worldwide, averaging 52 killings every hour. The global homicide rate was at 5.8 for every 100,000 persons, a number that sadly reflects little progress in reducing lethal violence worldwide since the launch of the 2030 Agenda for Sustainable Development in 2015. The biggest share of the victims were killed with firearms, which accounted for 47 per cent of homicides committed with a known mechanism worldwide. That number rises to 75 per cent in the Americas, which has the highest homicide rate in the world, and where organized crime is responsible for at least half of all homicides. In different parts of the world, organized crime can lead to spikes in homicide, particularly as criminal groups compete for control. Organized crime has also had an impact on homicide rates in Europe. While the regional homicide rate has decreased over the last six years, there are signs of increased lethal violence connected to organized crime in various countries of the continent. Such organized crime-related killing – and all homicidal violence, in all parts of the world – is far more likely to be committed by, and against, men. Men account for 81 per cent of the victims of intentional homicide globally, and around 90 per cent of the suspects. Women, on the other hand, are more likely to be killed because of their gender, and more likely to lose their lives to violence at home. Women account for the victims in 54 per cent of killings in the home, and 66 per cent of intimate partner killings. Many people are also killed because of what they do, including human rights defenders, humanitarian workers, journalists, and environmental activists. The current global situation, characterized by growing conflicts and rule of law challenges, is fuelling such sociopolitical homicides, which in many cases happen with impunity. Given the broad and diverse factors driving lethal violence around the world, effective responses to homicide must cover a wide spectrum of context-specific interventions. Some interventions will be designed to reduce genderbased violence against women and girls, others will be geared towards reducing organized crime and gang violence, and others still may focus on firearm laws and regulations, vocational training to at-risk demographics, or mental health interventions. But all responses must share common threads, namely the need to be based on evidence, the need to prioritize prevention and address root causes, and the need to invest significantly. Investing in homicide prevention and responses is of particular priority in Africa, which this Global Study projects to be the most at-risk region over the coming decades, in large part due to its younger population, economic inequality levels, climate vulnerability, and weaker response capabilities. This study also highlights the significant limitations in the information available across regions, and the need to invest in better data collection. It is highly important to understand the types of homicide in any given context, whether family-related, gang-related, or any of the other identified typologies, yet more than a third of all detected homicides are classified as “unknown”. Similarly, four out of every ten killings of women and girls do not have information on the victim-perpetrator relationship, despite the prevalence of intimate partner killings against women and girls.

Illicit drugs continue to be a profitable area for criminal organizations operating within the EU. Drug use and drug markets can act as facilitators for all types of violence, which could ultimately lead to homicide. Yet, drug-related homicide (DRH) has not been monitored. The development of a drug-related homicide data collection is necessary to study this phenomenon. This report provides a first step towards a European-level DRH monitor.
