Abstract

Homicide as the most serious form of lethal violence has always represented an important research focus in criminology. Much of the existing research, however, is based on aggregated homicide data and is limited to macrolevel analyses. The European Homicide Monitor (EHM) is an initiative promoting standardized international data collection, with the aim of collecting disaggregated and detailed data on homicide. Originally developed by researchers from the Netherlands, Sweden, and Finland, the EHM coding scheme is currently applied in several European countries. In this article, we take stock of the use of the EHM approach by describing its key principles and aims. We also review research conducted within the EHM framework and identify the most significant developments in its use, such as expanding to the Global South, to the historical past, and to more accurate measurement of drug-related incidents. We conclude this investigation by discussing the challenges facing future research in this domain.

... Practically speaking, there are several initiatives to establish databases that facilitate international comparison. The WHO Mortality Database tends to be the standard (Rogers & Pridemore, 2023), alongside this we see the development of initiatives such as the European Homicide Monitor (Kivivuori et al., 2024;Liem et al., 2013) that currently covers Sweden, Finland, the Netherlands, and Switzerland (with partial coverage in Denmark, Estonia, and France), is beginning to be implemented in the Caribbean, Indonesia, and South Africa; the instrument is thus potentially evolving towards a Global Homicide Monitor. Only by drawing on such instruments designed for research, can we explore whether the theories and explanatory frameworks apply globally. ...
... As a result, we are still far from a full understanding of the various sociocultural aspects, such as collectivism and honor, in play in female homicide victimization among non-Western societies (Dayan et al., 2022). Efforts are under way to expand the EHM concept to non-European areas, including the Dutch Caribbean and South Africa (Kivivuori et al., 2024). These efforts will hopefully reveal to what extent the heterogeneity of female homicide victimization can be observed elsewhere-and what is needed to bring such forms of lethal violence down further. ...

Recent years witnessed an increase in attention to femicide, or the killing of women because of their gender. Prior empirical studies have drawn attention to the prevalence of female homicide victimization, but most have been unable to give a detailed overview of the specific contexts in which women are killed, and to what extent female homicide victimization is unique, i.e., in that it differs from male victimization. This exploratory study aims, first, to map the nature and scope of female homicide in six European countries: Denmark, Finland, France, the Netherlands, Sweden and Switzerland; and, secondly, to compare female homicide victimization with male homicide victimization. Using data from a new uniform homicide recording system, the European Homicide Monitor, this study allowed for unique cross-country comparisons and a detailed breakdown by victim-offender relationship, and type of homicide. Results indicated that female homicide victimization rates remained relatively stable during the last decade, with a narrowing gender gap. Furthermore, results reflected substantial heterogeneity in the context in which women were victimized. Finally, female homicide victimization differs in many respects from male victimization, but overlaps do exist. Such heterogeneity, and possible overlaps with male victimization call for differential approaches.

Homicide remains a major cause of death globally. The global risk differentials are a persistent public health challenge. Africa’s homicide rate of 13 victims per 100,000 people is markedly higher than the European average (2.2 per 100,000 people). To understand the causes of such large differences, homicide research needs to move from country-level rates to disaggregated analyses in which homicide is broken down by victim, offender, and incident characteristics. We conducted a pilot study in which the European Homicide Monitor (EHM) coding manual is applied to a South African research location and compared to an extreme point in the Global North, Finnish urban areas. We find differential patterns in the two locations. The high-rate context of South Africa manifests a younger offender and victim age structure, a higher share of criminal and revenge motives and the use of firearms, and incidents in public places. In contrast, the comparatively low-rate Finnish context shows a higher relative share of intimate partner violence and familial incidents taking place in private places. The role of alcohol and drugs appears more salient in Finnish urban homicide, a finding calling for replication. We conclude by discussing the methodological challenges revealed by the pilot comparison.

Homicide statistics are often used as an indicator for violent crime more generally. In this work, we evaluate the empirical support for this convention in a Western European context, specifically the Netherlands. Using data from Statistics Netherlands (CBS) and from the Dutch Homicide Monitor, we compare homicide rates to rates of other violent crimes between 2010 and 2020. Results show that homicide and violent crimes are related in a general sense, but it is difficult to say what those relationships look like concretely. In other words, there is an empirical relationship between homicide and the overarching concept of violent crime, but relationships between homicide and individual violent crimes vary considerably. Based on these findings, we advise that researchers tread carefully when using homicide as an indicator of violent crime.

Aim This paper aims to better understand the relationship between homicide and other public health outcomes, by studying their trends over time. Subject and methods Research in both criminology and public health has long identified that crime and violence tend to cluster together with adverse phenomena in the social and health domains. However, such work has relied primarily on cross-sectional analyses. Here, we instead study trends over time. We take data from the Netherlands, between 2000 and 2020, and ask whether homicide shows similar trends over time as other public health phenomena – such as smoking behaviour, alcohol use, child mortality, adolescent pregnancies, and suicide. Results We observe, first, that all of the phenomena – with the exception of suicide – declined over the period under study. We then employ a time series analysis to examine whether these trends arise independently, or whether they are the result of structural similarities between phenomena. Results showed that the decline in homicide rates is linked to a similar decline in adolescent pregnancies – the rates of these phenomena ‘move together’ during the period under study. Conclusion This work shows that the phenomenon of homicide shares structural similarities with teenage pregnancies – a decline in one is linked to a similar decline in the other. More generally, the current work furthers our understanding of the place of homicide in the domain of (public) health.

Detailed, comparative research on firearm violence in Europe is rare. Using data from the European Homicide Monitor, this paper presents the prevalence and characteristics of firearm homicides in Denmark, Finland, the Netherlands, Sweden and Switzerland between 2001 and 2016. Furthermore, we compare firearm to non-firearm homicides to assess the degree of uniqueness of firearms as modus operandi. We find that the firearm homicide rate varies across our sample of countries. We also identify two country profiles: in Denmark, the Netherlands and Sweden, most firearm homicides take place in public and urban areas, involving male victims and perpetrators. In these countries, the use of firearms in homicides is largely concentrated in the criminal milieu. In Finland and Switzerland, firearms are mostly used in domestic homicides, with a higher share of female victims. We explore these findings in relation to firearm availability in each country.

Homicide rates are often used as an indicator of levels of crime. The reasons for this are both practical and conceptual. Practically speaking, homicide statistics tend to be more reliable than statistics for other forms of crime. Conceptually speaking, homicide and other forms of crime are often considered to be related: homicide is seen as the “tip of the iceberg” of underlying crime. However, it remains unclear whether this convention is empirically justifiable. Here, we review empirical evidence for the idea that homicide can serve as an indicator of crime more generally. We identify 31 previous studies that include information on this issue. Findings indicate that homicide is related to other forms of crime (particularly violent crimes) in larger scale, and cross-sectional analyses, but studies focusing on smaller levels of analysis identify substantial variation depending on location or time frame being considered. We conclude that homicide can function as an indicator of violent crime in general, but no clear pattern emerges as to what that means concretely. To those authors wishing to use homicide as an indicator of (violent) crime, we recommend that they conduct and report preliminary work to establish to what extent this notion is justified within the context and time frame on which they wish to focus.

In this project we examine whether homicide ‘clusters together’ with other adverse health outcomes in the Netherlands, focusing on child mortality, suicide, sexual risk behavior, and substance abuse. We expected moderate-to-strong correlations between homicide and the other adverse health phenomena (hypothesis 1). Further, we expected that these correlations would be reduced when social disorganization is controlled for (hypothesis 2). The study used population-level data between the years 1996 and 2019, for each of the 40 local regions of the Netherlands. We applied a multilevel correlation procedure to evaluate correlations between homicide and the other adverse health outcomes. Correlations between homicide and the other adverse health outcomes were modest. That is, we found only limited evidence for clustering between homicide and the other adverse health outcomes. The patterns of clustering that did occur, suggested that social disorganization in the region promotes risk-taking behaviors in the population, which ultimately increases rates of homicide, abuse of illegal drugs and births to adolescent parents.

This study examines homicide trends in seven European countries – Denmark, Estonia, Finland, the Netherlands, Scotland, Sweden and Switzerland – all of which manifested a substantial drop in homicide mortality between 1990 and 2016. By using data from the European Homicide Monitor, a coding scheme created to enable cross-country comparisons, combined with the national cause-of-death statistics, we explore generality versus specificity of the homicide drop. We examine changes in the demographic structure of victims and offenders and disaggregate homicides by different subtypes of lethal incidents, such as family-related homicides referring to conflicts between family members, and criminal milieu homicides occurring in the context of robberies, gang-related conflicts or organised crime. Results point to the generality of the drop: in most of the countries studied, the declining trend included all homicide types. The overall decline in homicide mortality was driven mostly by the decline in male victimisation and offending. In most of the countries, the gender distribution of victims and offenders changed only slightly during the study period, whereas the development of the distribution of homicide types manifested greater diversity. Our findings illustrate the benefits of disaggregated analyses in comparative homicide research.

This systematic review examined the evidence on factors influencing the flow of homicide, from suspicious death to imprisonment. Bibliographic databases and thesis portals were searched. The total number of hits was 15,986, of which 15,830 were irrelevant, 35 did not include a quantitative sample, 26 did not focus on homicide, 18 did not present flow data, and for seven there was no full text available. The remaining 70 papers were analyzed. With the exception of one, no study presented a complete longitudinal flow. Results indicated that both legal and extralegal characteristics influence the likelihood of cases to drop out. Aside from a first mapping of homicide case flows, future research should explore false positives and false negatives, to come to a first understanding of funnel selectivity in homicide cases.

The likelihood that homicides lead to arrest, conviction, and incarceration of the perpetrators varies widely across world regions. To date, we lack a comprehensive framework that can explain the differences in how homicide cases are processed in different jurisdictions, and how this knowledge can be used to hold perpetrators to account, to advance the rule of law, and to promote equal access to justice. This Special Issue seeks to advance the cross-national and comparative analysis of homicide case flows, from suspicious death to imprisonment. In this Introduction, we outline some analytic priorities that may help in moving the field forward.

This study provides an overview of homicide clearance in four West European countries: Finland, the Netherlands, Sweden and Switzerland. Using data from the European Homicide Monitor, employing similar definitions and uniform coding schemes, this study allowed for unique crosscountry comparisons in factors influencing differences in homicide clearance rates. Findings based on homicides occurring in the period 2009-14 revealed overall low homicide rates in all countries, with a wide variety in homicide clearance rates, ranging from 77 percent in the Netherlands to 98 percent in Finland. Results further showed that both event-based as well as victim-based characteristics significantly influenced the likelihood of homicide clearance, suggesting that homicide clearance rates can, for a large part, be attributed to the prevalent types of homicide in each of these European countries.

Purpose: Research addressing intimate partner homicide (IPH) across time and gender is lacking. The present study compares rates of IPH and non-intimate partner homicide (non-IPH) over time. Moreover, gender-specific trends of IPH rates and characteristics are examined. Methods: The study is based on all solved homicides (N = 1725) in Sweden between 1990 and 2013. The dataset is an extension of the European Statistical Database on Lethal Violence and holds information from police files, court verdicts and forensic psychiatric reports. Results: There has been a significant decrease of IPHs and non-IPHs, although, IPHs remained relatively stable until 2006. While there has been a modest decline in male-perpetrated IPHs, the low rates of female-perpetrated IPHs have remained stable. Male-perpetrated IPHs are gradually less likely to involve alcohol and be preceded by known history of IPV. The majority of female-perpetrated IPHs involved alcohol and history of known IPV, characteristics that remained stable over time. Conclusions: It is crucial to consider intimate relationships as well as gender in order to gain nuanced insight to trends of homicide rates and characteristics. Our findings demonstrate distinct trends across homicide types, as well as gender-specific rates and characteristics of IPH.

This study examines punishments for homicide in Europe by compiling national-level data and presenting a descriptive account of variation. We present original data collected from various European data sources and individual researchers and highlight the problems associated with cross-national data on homicide and the limitations this poses for research. Based on available data, we offer some preliminary observations regarding regional trends in homicide and incarceration rates for homicide. Finally, we provide some suggestions for how these problems might be overcome moving forward.

Due to differences in definitions, data sources and criminal justice procedures, comparing homicides between countries is not without problems. To overcome these limitations, we have constructed a joint European Homicide Monitor (EHM). So far, Finland, the Netherlands and Sweden constitute the basis of the database. In this contribution, we give an overview of this new data set. In doing so, we elaborate on methodological issues that arose when constructing this data set and discuss the feasibility of constructing an international and comparable homicide data set. Preliminary results show that the EHM as a joint database provides unique opportunities to closely monitor homicide across Europe.

Tötungsdelikte gehören zu den schwerwiegendsten Delikten mit gravierenden Folgen sowohl für die Angehörigen von Opfern und Tätern/Täterinnen als auch für das Sicherheitsgefühl der Allgemeinbevölkerung. Das vorliegende Buch basiert auf dem Swiss Homicide Monitor, einer Datenbank, die sämtliche vorsätzliche Tötungsdelikte in der Schweiz seit 1990 umfasst. Im Buch werden in anschaulicher Weise Informationen zu den Tätern/Täterinnen, Opfern, Tatumständen, den Motiven des Tötungsdelikts sowie zum Verfahrensablauf und zur rechtlichen Qualifikation aufgezeigt. Weiter werden einzelne spezifische Typen von Tötungsdelikten (Homizid-Suizide, Massen- und Serienmorde etc.) vertieft analysiert.

Nordic Homicide in Deep Time draws a unique and detailed picture of developments in human interpersonal violence and presents new findings on rates, patterns, and long-term changes in lethal violence in the Nordics. Conducted by an interdisciplinary team of criminologists and historians, the book analyses homicide and lethal violence in northern Europe in two eras – the 17th century and early 21st century. Similar and continuous societal structures, cultural patterns, and legal cultures allow for long-term and comparative homicide research in the Nordic context. Reflecting human universals and stable motives, such as revenge, jealousy, honour, and material conflicts, homicide as a form of human behaviour enables long-duration comparison. By describing the rates and patterns of homicide during these two eras, the authors unveil continuity and change in human violence. Where and when did homicide typically take place? Who were the victims and the offenders, what where the circumstances of their conflicts? Was intimate partner homicide more prevalent in the early modern period than in present times? How long a time elapsed from violence to death? Were homicides often committed in the context of other crime? The book offers answers to these questions among others, comparing regions and eras. We gain a unique and empirically grounded view on how state consolidation and changing routines of everyday life transformed the patterns of criminal homicide in Nordic society. The path to pacification was anything but easy, punctuated by shorter crises of social turmoil, and high violence. The book is also a methodological experiment that seeks to assess the feasibility of long-duration standardized homicide analysis and to better understand the logic of homicide variation across space and over time. In developing a new approach for extending homicide research into the deep past, the authors have created the Historical Homicide Monitor. The new instrument combines wide explanatory scope, measurement standardization, and articulated theory expression. By retroactively expanding research data to the pre-statistical era, the method enables long-duration comparison of different periods and areas. Based on in-depth source critique, the approach captures patterns of criminal behaviour, beyond the control activity of the courts. The authors foresee the application of their approach in even remoter periods. Nordic Homicide in Deep Time helps the reader to understand modern homicide by revealing the historical continuities and changes in lethal violence. The book is written for professionals, university students and anyone interested in the history of human behaviour.

This Element examines an increasingly important community crime prevention strategy - focused deterrence. This strategy seeks to change offender behavior by understanding underlying crime-producing dynamics and conditions that sustain recurring crime problems, and implementing a blended set of law enforcement, community mobilization, and social service actions. The approach builds on recent theorizing on optimizing deterrence, mobilizing informal social control, enhancing police legitimacy, and reducing crime opportunities through situational crime prevention. There are three main types of focused deterrence strategies: group violence intervention programs, drug market intervention programs, and individual offender programs. A growing number of rigorous program evaluations find focused deterrence to be an effective crime prevention strategy. However, a number of steps need to be taken to ensure focused deterrence strategies are implemented properly. These steps include creating a network of capacity through partnering agencies, conducting upfront and ongoing problem analysis, and developing accountability structures and sustainability plans.

An extensive body of criminological research has shown that criminal and violent behaviour manifests time patterns in terms of daily, weekly and annual cycles. This is consistent with criminological routine activities theory. Can we generalize these patterns to historical periods? In this article, we draw on a recently created unique dataset, covering the years 1608–1699 in three Nordic regions, to explore time cycles of offending in the early modern period. Examining daily, weekly and annual cycles, we find that lethal violence manifested strong time patterns in the early modern period. The role of public holidays was central especially in the period lasting from Christmas to Midsummer. Probing the role of key routines, we disaggregated the composition of homicide cycles by alcohol use and place of occurrence. The findings indicated that early modern homicide time cycles were associated with alcohol use and activities in private places. We conclude by discussing the strengths and limitations of our data and by suggesting further research in the promising frontier of standardized long duration homicide research.

Background: Drugs can act as facilitators for all types of violence, including drug-related homicide (DRH). Addressing this phenomenon is not only of importance given the severity of a homicide event and its high costs on society, but also because DRH has the potential to act as a valuable indicator or proxy of wider drug-related violent crime. However, there appears to be an important gap in terms of available European data on DRH. This study aimed to identify relevant European data sources on DRH, to assess the role of drugs in national homicide data, and to assess these sources and data in terms of monitoring potential. Methods: A critical review was conducted of existing national and international homicide data sources. A three-step approach was adopted, including systematic searches for data sources and literature, snowballing methods, and contacting professionals. Results: Data on DRH is systematically prepared in the Czech Republic, Denmark, Finland, Germany, Italy, the Netherlands, Norway, Slovakia, Sweden, and the United Kingdom (England, Wales, and Scotland). Available data suggests both between- and within country variability in relation to the role of drugs in homicide events. Based on these findings, four key obstacles can be identified in terms of the current ability to monitor DRH: missing data, fragmented data, comparability issues and data quality reservations. Conclusion: To overcome these obstacles, there is a need for an international monitoring system that incorporates DRH. Ideally, the system should employ a single shared definition, standardised terminology, one coordinating body, and the use of multiple data sources. There are several approaches towards such a system, notably expanding the European Homicide Monitor (EHM) framework. Options should be explored to incorporate DRH into this existing and growing monitoring system.

After a high-profile homicide case, there is often discussion in the media on whether or not the killing was caused or facilitated by a psychotropic medication. Antidepressants have especially been blamed by non-scientific organizations for a large number of senseless acts of violence, e.g., 13 school shootings in the last decade in the U.S. and Finland (1). In September 2014, there were more than 139,000 hits from Google for the search terms “antidepressant, homicide”, and more than 1,050,000 hits for the terms “antidepressant, violence”. It is likely that such massive publicity in the lay media has already led a number of patients and physicians to abstain from antidepressant treatment, due to the perceived fear of pharmacologically induced violence.

This special issue brings together original contributions by scholars from various disciplines that examine how evolutionary and historical research can advance our understanding of violence. In combining archaeological, anthropological, biological, sociological, and historical research the papers outline a perspective that transcends the conventional boundaries of criminology. Its core feature is the idea that we need a better understanding of the interaction between the evolutionary forces that shape the universal mechanisms associated with violence, and the ways in which social institutions, beliefs and structures of daily life control or amplify the potential for violent action.

Five important changes can be detected in the homicidal crime of Finland and Sweden. From the mid-seventeenth century to the mid-eighteenth, concurring with the establishing of the modern centralized state, homicide rates dropped significantly. In the long term, the local variation in Swedish homicide rates decreased, probably because of the rise of the centralized state; however, the case was different in Finland, partly because of a less efficient central administration before the twentieth century. During the period 1700–2000, there was a clear social marginalization of lethal violence; this change took place earlier in Sweden than in Finland. There was a relative shift from instrumental (economy-related) to expressive violence. In the twentieth century, concurring with general urbanization, there was a considerable privatization of lethal violence in both countries as homicides moved from public places to private. The social and historical data suggest that homicide participants may have become more deviant from the mainstream society than they used to be. Overall, Nordic homicidal crime has had two major components since the early modern period. The high offending rates of the marginal lowest-stratum male population have been a stable phenomenon for five centuries. Sudden changes in homicide rates have typically been caused by young males with more heterogeneous social backgrounds.

Cross-national research has increased in the past few decades, resulting in a large body of empirical research. In particular, cross-national studies are often limited in data sources, which restrict variable selection to debatable proxy indicators. This study therefore uses meta-analytic techniques to examine major cross-national predictors of homicide to determine strengths and weaknesses in theory and design. The findings indicate several critical limitations to cross-national research, including biased sample composition, a lack of theoretical clarity in predictor operationalizations, and an overwhelming reliance on cross-sectional design. The predictors that showed the strongest mean effects were Latin American regional dummy variables, income inequality indicators and the Decommodification Index. Conversely, static population indicators, democracy indices, and measures of economic development had the weakest effects on homicide.
Article
In the early 1960s, 15% of Finnish homicide offenders committed suicide after the crime. In 1998-2000, this ratio was 6%. The downward trend was due to the increase in non-suicidal homicide, as well as to a substantial decrease in the general homicide-suicide rate. Over the time span, the rate of suicidal homicide offenders per 100,000 population was halved. The decrease took place in the two most significant homicide-suicide types (that is, those of intimate-partner homicides and parent-child killings) and, within these crime types, in crimes committed by men. The present article describes the prevalence and trend of homicide-suicide in Finland, and examines the socio-economic correlates of this phenomenon. The findings indicate that the percentage and the rate of homicide-suicide have been consistently highest among middle classes and lowest among the unemployed and working classes. Victim-offender relationship, stressful life events, and alcohol consumption are discussed as explanations for this stable social difference.
