This review takes stock of recent advances, as well as enduring and emerging challenges, in the area of spatial criminology. Although the notions of place and space are fundamentally intertwined, spatial criminology is distinct in its attempt to measure and theorize explicitly spatial processes and relationships. This review highlights three key themes. First, the use of increasingly smaller geographic units in recent research creates an even greater need to account for spatial behavior of persons when studying the location of crime. Second, although the explosion of spatially precise data in recent years presents exciting possibilities, we argue that theory is falling behind in guiding us in analyzing these new forms of data, and explicitly inductive approaches should be considered to complement existing deductive strategies. Third, an important direction for spatial criminology in the next decade is considering the extent to which micro- and mesolevel processes operate invariantly across different macro contexts.

Nowadays, 23% of the world population lives in multi-million cities. In these metropolises, criminal activity is much higher and violent than in either small cities or rural areas. Thus, understanding what factors infuence urban crime in big cities is a pressing need. Seminal studies analyse crime records through historical panel data or analysis of historical patterns combined with ecological factor and exploratory mapping. More recently, machine learning methods have provided informed crime prediction over time. However, previous studies have focused on a single city at a time, considering only a limited number of factors (such as socio-economic characteristics) and often at large in a single city. Hence, our understanding of the factors influencing crime across cultures and cities is very limited. Here we propose a Bayesian model to explore how violent and property crimes are related not only to socio-economic factors but also to the built environment (e.g. land use) and mobility characteristics of neighbourhoods. To that end, we analyse crime at small areas and integrate multiple open data sources with mobile phone traces to compare how the different factors correlate with crime in diverse cities, namely Boston, Bogotá, Los Angeles and Chicago. We fnd that the combined use of socio-economic conditions, mobility information and physical characteristics of the neighbourhood effectively explain the emergence of crime, and improve the performance of the traditional approaches. However, we show that the socio-ecological factors of neighbourhoods relate to crime very differently from one city to another. Thus there is clearly no “one fits all” model.

Police-reported crime data (hereafter “crime”) is routinely used as a psychosocial stressor in public health research, yet few studies have jointly examined (a) differences in crime exposure based on participant race and ethnicity, (b) differences in measures of crime exposure, and (c) considerations for how exposure to police is captured in police-recorded crime data. We estimate neighborhood exposure to crime and discuss the implications of structural differences in exposure to crime and police based on race and ethnicity. Methods. Using GPS coordinates from 1188 participants in the Newborn Epigenetics Study, we estimated gestational exposure to crime provided by the Durham, North Carolina, Police Department within (a) 800 m and (b) the Census block group of residence. We controlled for non-overlapping spatial boundaries in crime, Census, residential, and police data to report crime spatial (crime per km2) and population (crime per 1000 people per km2) density. Results. We demonstrate dramatic disparities in exposure to crime based on participant race and ethnicity and highlight variability in these disparities based on the type of crime and crime measurement method chosen. Conclusions Public health researchers should give thoughtful consideration when using police-reported crime data to measure and model exposure to crime in the United States, as police-reported data encompasses joint exposure to police and crime in the neighborhood setting.

Crime is a costly societal issue. While many factors influence urban crime, one less-studied but potentially important factor is neighborhood greenspace. Research has shown that greenspace is often negatively associated with crime. Measuring residents’ use of greenspace, as opposed to mere physical presence, is critical to understanding this association. Here, we used cell phone mobility data to quantify local street activity and park visits in Chicago and New York City. We found that both factors were negatively associated with crime, while controlling for socio-demographic factors. Each factor explained unique variance, suggesting multiple pathways for the influence of street activity and greenspace on crime. Physical tree canopy had a smaller association with crime, and was only a significant predictor in Chicago. These findings were further supported by exploratory directed acyclic graph modeling, which found separate direct paths for both park visits and street activity to crime.

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.

Objectives. To describe associations between neighborhood racial and economic segregation and violence during the COVID-19 pandemic. Methods. For 13 US cities, we obtained zip code-level data on 5 violence outcomes from March through July 2018 through 2020. Using negative binomial regressions and marginal contrasts, we estimated differences between quintiles of racial, economic, and racialized economic segregation using the Index of Concentration at the Extremes as a measure of neighborhood privilege (1) in 2020 and (2) relative to 2018 through 2019 (difference-in-differences). Results. In 2020, violence was higher in less-privileged neighborhoods than in the most privileged. For example, if all zip codes were in the least privileged versus most privileged quintile of racialized economic segregation, we estimated 146.2 additional aggravated assaults (95% confidence interval = 112.4, 205.8) per zip code on average across cities. Differences over time in less-privileged zip codes were greater than differences over time in the most privileged for firearm violence, aggravated assault, and homicide. Conclusions. Marginalized communities endure endemically high levels of violence. The events of 2020 exacerbated disparities in several forms of violence. Public Health Implications. To reduce violence and related disparities, immediate and long-term investments in low-income neighborhoods of color are warranted.

This thesis examines the emergence and sustainment of milícias (militias) in the 1990s in the West Zone ‘margins’ of the city of Rio de Janeiro. It considers the rise of milícias as they coincide with urbanisation, economic liberalisation, democratisation, decentralisation and the rise of violent drug trafficking organisations. This thesis sets out to answer the following overarching research question: ‘How and why did milícias emerge in Rio de Janeiro’s West Zone since the 1990s and how and why were they sustained? What is their relationship to the management of (dis)order?’ The analytical approach developed to answer this question draws on an historically situated political settlements framework to understand milícias as power relations within coalition formations and as facilitators of rent extraction and distribution. The framework introduces urban and political geography literatures on frontiers to advance a thesis that milícias in Rio de Janeiro are coercive brokers that mediate urban frontier zones. This study draws on ethnographic fieldnotes from direct and participant observation, in-depth interviews and oral histories, and extensive archival research of parliamentary documents. It argues that milícias emerged to provide temporary ‘solutions’ to address the violent inequalities, structural insecurities, and the threats and insecurities posed by drug trafficking organisations in the urban frontiers. They emerged through ‘bottom-up’ processes but were also seen as convenient to political and economic elites in the central state who were unable (or unwilling) to provide formal security in the West Zone. However, this thesis makes the case that there was a trade-off for the central state as paramilitaries, as accrued power in the urban frontier, they also attempted to reshape state institutions. Because of their roots in local communities, this thesis also recognises the dependency of milícias on legitimacy, ideas, beliefs and norms, and the power imbued in community relations. This study contributes to the literatures on milícias by accounting for their role as co-producers of (dis)order in the urban margins, the literature on political settlements by intertwining questions of violence and conflict with spatiality, and finally the Latin American literatures on local political order and governance by advancing a conceptualisation of armed groups straddling state and society and challenging conventional state/-non-state binaries.

This thesis presents two individual research papers that examine the relationship between greenspaces and crime in Portland, Oregon. The two papers use an adapted street network buffer to better measure crime concentration around discrete locations. This methodological development allows for an improved measure of crime concentration around discrete locations. The first contribution, presented in Chapter 2, explores the relationship between different greenspace types and crime, breaking down different crime types into discrete categories. The results of this study suggest that overall, Portland greenspaces do not experience a concentration of crime, however, different patterns emerge as greenspace and crime types are disaggregated. Only one greenspace type, small parks, appear to be important local features—experiencing a high concentration of crime—while other types experienced a concentration of a few crime types, or none at all. Building off of these results, the second contribution—Chapter 3—examines the relationship between small parks and crime in more detail, looking at the level of crime concentration beyond the park, the presence of certain amenities, and the surrounding landuse zoning. A non-linear pattern in the level of crime concentration was found in the 3- block area around parks. Three park characteristics (statues/public art, water features/fountains, and plazas) were found to be associated with higher levels of crime at parks, while one characteristic (unpaved paths) and two activity generators (soccer fields and softball fields) were associated with lower levels of crime. The surrounding zoning also had an impact on crime at parks, with parks with exclusively or majority residential land use experiencing lower levels of crime.

The study takes up the pertinent challenges in human rights work of consistent lacks, deficiencies and uncertainties in human rights work and human rights reporting. These challenges pose questions to the human rights community on how to provide reliable information on violence, torture and ill-treatment, which includes the detection and identification of both victims and perpetrators necessary to ensure individual justice and institutional accountability. The report demonstrates that it is possible to address sensitive political issues of governance and violence, even in a nervous political setting, and produce relevant and solid data on violent encounters, that describes the unfolding of these events and the effects on life and livelihood, including health and economy, of the individuals and families involved. The richness and depths of the data confirms the usefulness of the methodological approach, at least in Korail Basti in the centre of Dhaka. It indicates a potential for broader and hopefully general applicability in other similar areas of the city, the country or the region and perhaps even at a global level. Confirming this general applicability would entail the need to replicate, adapt and carry through the study in additional sites and places with other contextual social, political and economic conditions and configurations. The solidity of the survey’s findings is a promising result of the study and could be a possible departure point for further testing of the proposed methodology

In this report, Global Financial Integrity (GFI) presents an analysis of narcotics-related illicit financial flows between the United States and the major narcotics production and transit countries of Mexico and Colombia. The report was commissioned by the Western Hemisphere Drug Policy Commission as part of its mandate to evaluate US drug policies and programs in Latin America and the Caribbean, assess current efforts to reduce the illicit drug supply and address the harms associated with trafficking and drug abuse. A variety of strategies can and have been used to address drug trafficking in the Western Hemisphere, from manual and aerial crop eradication, to interdiction, illicit crop substitution and other alternate development approaches. While existing strategies have resulted in temporary disruptions to narcotics cultivation and trafficking, they have not been successful in addressing these issues in a comprehensive, lasting manner. At the same time, history has shown that many of these policies have had unintended consequences and caused harm to people, their communities and the environment in very profound ways. Financial strategies from the anti-money laundering and counter financing of terrorism (AML/CFT) toolkit offer a different lens to view and address the problem of drug trafficking. In this report, GFI argues that AML/CFT is underutilized in current US and regional counter-narcotics efforts and needs to be reprioritized. Effectively responding to the challenges of drug trafficking and transnational organized crime will require a multi-pronged, multi-stakeholder and multi-disciplinary effort that includes AML/CFT, as well as a more comprehensive approach to drug policies that encompasses human rights, public health and development.

Fare and toll evasion is a sensitive issue that raises difficult questions about social cohesion, inequality, and appropriate use of enforcement. But the situation in New York has reached a crisis level, and avoiding the topic is no longer a viable option. Losses to the MTA’s operating budget are staggering, with nearly $700 million in revenue not collected in 2022 alone. This includes $315 million lost in bus fares, $285 million in subway fares, $46 million in bridge and tunnel tolls, and $44 million in railroad fares. Fares and tolls account for a significant proportion of the MTA’s annual budget revenue — almost $7 billion a year. But every dollar lost to evasion impairs the MTA’s financial stability, threatens reliable transit for all New Yorkers, and increases the need for alternative revenue sources, including through larger fare and toll hikes. The MTA convened a Blue-Ribbon Panel of high-profile New Yorkers with expertise in relevant fields to better understand fare and toll evasion, and develop fresh solutions to the issue. Panelists spent the better part of a year meeting with stakeholders inside and outside the MTA, speaking with transit users, and observing fare and toll collection operations throughout the system. The panel’s final report proposes a cohesive and comprehensive set of strategies around education, environment, equity, and enforcement.

This review provides a summary of the evidence on Illicit Financial Flows (IFFs) between China and developing countries in Africa and Asia. Specifically, it looks at the evidence on how IFFs to and from China impact on developing countries, as well as on the drivers of IFFs and of how flows are facilitated. The review draws upon a combination of academic and grey literature sources, though it is not exhaustive and only draws upon English language sources. IFFs involving China have attracted particular attention, due to estimates suggesting it is responsible for the largest IFFs by value globally. However, little has been published to date specifically on IFFs between China and developing countries. This paper attempts to help address this gap. Section 2 provides some background information on the debates and uncertainties around IFFs, including conceptual issues, difficulties in measuring these flows, and their potential impacts, as well as attempts to quantify China’s overall IFFs. Section 3 focuses on trade-related IFFs between China and developing countries in Asia and Africa. Discrepancies indicative of potential IFFs are identified using trade data from 2018 and an attempt is made to determine the scale of the revenue consequences of trade is-invoicing for China’s developing country partners. Section 4 considers IFFs-related to corrupt business practices, focusing largely on Chinese investment in Africa. Section 5 moves on to consider IFFs that relate to the trade in illegal products, including illegal narcotics, human trafficking, the illegal arms trade, the illegal wildlife trade, the illegal organ trade, and the trade-in counterfeit products. Finally, Section 6 discusses enabling environment factors relevant to IFFs between China and developing countries.

With the increase in Internet coverage, online trade of illicit goods is likely increasing on the African continent. In recent years, cyber-enabled crimes have increased on the African continent. This has been a result of a combination of factors, including, the improvement of Internet coverage, the wide availability of cyber-tools and the growing flexibility of cybercriminals. As a consequence, online crime nowadays represents a bigger security issue for law enforcement in African member countries than ever before. In this framework, INTERPOL, under the European Union funded ENACT Project, examines through this assessment the issue of cyber and cyber-enabled crimes in Africa in order to help drive a more strategic law enforcement response.

The development of mobile money services in Africa offer criminals a substantial opportunity to utilize these services to target victims in a variety of crimes as well as to further enable other forms of criminality. This rapid service development combined with criminal opportunities represents a security issue of interest to all member countries in Africa and poses a significant challenge to law enforcement agencies in member countries. As a result, INTERPOL, under the European Union funded ENACT Project, has assessed this issue in order to help drive a more strategic law enforcement response. Criminals and criminal organizations will most probably continue to utilize mobile money services following the recent increase in their popularity and the prominent role such services now play in society across Africa. This prominent role in society has enabled criminals to exploit weaknesses in regulations and identification systems, further enabled by a lack of experience and resources in law enforcement. Crime types have been identified that exploit mobile money services across Africa. These primarily include various types of fraud that target the distinct stages of deployment for mobile money services. Whilst acquisitive crimes significantly impact the lives of victims, criminals have also identified further opportunities to exploit mobile money services to assist other criminal activities. These ‘mobile money enabled crimes’ include illicit commodities purchases, terrorism financing and firearm enabled crime. Such significant crimes pose a threat to stability and security across Africa if not addressed by member countries. The threat from criminality facilitated by mobile money services in Africa is substantial, yet there is sometimes limited capacity amongst law enforcement to manage this complex issue, especially concerning the technical expertise required to utilise relevant evidence in the criminal justice system. As mobile money services develop interoperability across Africa, stronger partnerships amongst all law enforcement agencies, greater awareness of the overall issue at a regional level and identification of best practice responses from such agencies will be required. INTERPOL is in a position to support member countries through coordinated, intelligence led support to law enforcement using a range of police databases and operational support techniques.

We provide the first quantitative synthesis of the literature on how financial markets react to the disclosure of financial crimes committed by listed firms. While consensus expects negative stock price returns, the exact size of the effect is far from clear. We surveyed 111 studies published over three decades, from which we collected 480 estimates from event studies. Then, we perform a thorough meta-analysis based on the most recent available techniques. We show that the negative abnormal returns found in the literature seem to be exaggerated by more than three times. Hence, the “punishment” effect, including a reputational penalty, suffers from a serious publication bias. After controlling for this bias, negative abnormal returns suggest the existence of an informational effect. We also document that accounting frauds, crimes committed in common-law countries such as the United States, and allegations are particularly severely sanctioned by financial markets, while the information channels and types of procedures do not influence market reactions.

This paper explores the links between digital vigilantism and organised crime in South Africa and Kenya.

Social media platforms have become powerful tools to amplify and share narratives. Like many evolving technologies, platforms such as Twitter or Facebook may be used for social good or for ill. Digital vigilantism (whereby social media platforms are used for organised shaming, hounding or doxing of a target deemed by the online community to have transgressed norms) may have real-world consequences. In extreme cases this may result in acts of ‘terrorism’ or other forms of unlawful killing. Yet while digital vigilantism may appropriate traditional law enforcement mechanisms, in some cases it may also try to hold law enforcement to account.

Cybercrime, in its various forms, represents an increasing threat to the EU. Cyber-attacks, online child sexual exploitation, and online frauds are highly complex crimes and manifest in diverse typologies. Meanwhile the perpetrators behind these crimes are becoming increasingly agile, exploiting new situations created by geopolitical and technological changes. The Internet Organised Crime Assessment (IOCTA) is Europol’s assessment of the cybercrime landscape and how it has changed over the last 24 months. Accompanying this report will be a series of spotlight reports released later this year, each of which examines a specific crime area relating to cybercrime.

I have explored how to improve cybercrime reporting in Scotland by conducting a systematic literature review. Due to the lack of data on Scotland, I have frequently extrapolated from both the UK and the West. The research questions were: 1. What is known about cybercrime in the UK to date? 2. What is known about cybercrime victims in the UK to date? 3. What is known about cybercrime reporting to date? The answers were retrieved by combining Boolean variables with keywords into Scopus, Web of Science and ProQuest. This resulted in the analysis of 100 peer-reviewed articles. This analysis revealed a common trend, a novel taxonomy, and an original conclusion. The common trend is that of responsibilisation, which is the shifting of responsibility for policing cybercrime from the government onto the citizens and private sector, which will inevitably responsibilise consumers. The novel taxonomy is for classifying cybercrime reporting systems according to three pillars, which I referred to as Human-ToHuman (H2H), Human-To-Machine (H2M) and Machine-To-Machine (M2M). The original conclusion is that to improve cybercrime reporting in Scotland, the process needs to be treated also as a social one rather than a purely mathematical one.
