  This report, compiled between September 2006 and March 2007, brings together data from two surveys, 54 interviews with ‘key informants’: professionals, local residents and young people involved with, or affected by, youth gangs. Key informants are marked like this (KI.01) in the text to indicate the source of the information. However, the report also draws on the many insights I have gained from informal conversations at Waltham Forest YOT over the period. The interview and survey data is augmented by a literature review. Some of the material presented here is straightforward reportage, but some of it is more speculative, based on inferences or hunches drawn from what respondents have said or what I have read. So when, in the text, I write ‘it appears’ or ‘it is said’, I am drawing on hearsay and hunches or making an inference that seems plausible to me but is not necessarily a castiron fact. As such, these kinds of assertions or conclusions should be read with caution. In the interests of anonymity this report does not name the key informants; yet without them this study would have been impossible.

Despite the growing body of qualitative evidence suggesting collusion between gangs and political parties in various parts of the world, little has been done to study quantitatively the extent to which criminal organization may affect political elections in such context. Using police data and voting results in El Salvador, we find that homicides in gang-controlled neighborhoods tend to decrease by 24 percent of the mean during electoral seasons. We also estimate that gang control is associated with a 2.75 percentage point increase in electoral participation. These effects are especially significant in the neighborhoods where political parties have a strong voting base. Consistent with the interviews we conducted, this suggests that parties negotiate with gangs to mobilize electoral participation in the areas where they are more likely to receive electoral support and thus increase their chances of winning. To conduct our analysis, we geolocated the homicides reported daily in the registry of the National Civil Police from 2005 to 2019 crossed with electoral results reported at the voting-center level across El Salvador. We exploit the sudden and exogenous decrease in criminality resulting from the 2012 truce between the government and the two main gangs in El Salvador to identify gang-controlled neighborhoods. We also use penitentiary data from the General Directorate of Prisons for robustness measures.

We study how territorial control by criminal organizations affects economic development. We exploit a natural experiment in El Salvador, where the emergence of these criminal organizations was the consequence of an exogenous shift in American immigration policy that led to the deportation of gang leaders from the United States to El Salvador. Upon arrival, the gangs gained control over many urban areas and re-created a system of borders to protect their territory from outsiders. Using a spatial regression discontinuity design, we find that individuals in gang-controlled neighborhoods have less material well-being, income, and education than individuals living only 50 meters away but outside of gang territory. None of these discontinuities existed before the arrival of the gangs. A key mechanism behind the results is that gangs restrict individuals’ mobility, affecting their labor market options by preventing them from commuting to other parts of the city. The results are not determined by high rates of selective migration, differential exposure to extortion and violence, or differences in public goods provision.

  The aim of the current study was to understand how gangs have changed in the past ten years since Pitts’ (2008) study in the London Borough of Waltham Forest. The study undertook interviews with 21 practitioners working on gang-related issues and 10 young people affected by gangs or formerly embedded in them. Two focus groups involving 37 participants from key agencies then explored the preliminary findings and contributed to a conceptualisation of a new operating model of gangs. The study found that local gangs had evolved into more organized and profit-oriented entities than a decade earlier. The new operating model rejected visible signs of gang membership as “bad for business” because they attracted unwanted attention from law enforcement agencies. Faced with a saturated drugs market in London, gangs moved out to capture drugs markets in smaller UK towns in “county lines” activities. This more business-oriented ethos has changed the meaning of both territory and violence  While gang members in the original study described an emotional connection with their postcode, territory is increasingly regarded as a marketplace to be protected. Similarly, violence has moved from an expressive means of reinforcing gang identity to being increasingly used as an instrumental means of protecting business interests. The current study offers a rare opportunity to gain a picture of gangs at two time periods and contributes to work on the contested nature of UK gangs and renewed interest in gang evolution. These findings have important implications for local authorities and criminal justice agencies who need to address directly the profit motive of gang activity.

Social media provide novel opportunities for street gangs to operate beyond their traditional borders to sell drugs, recruit members and control their territory, virtually and physically. Although social media have contributed to the means available to street gangs today, it does not mean that every gang agrees on their use. Drawing on different perspectives (ex-gang members, law enforcement) on gangs using a multi-method design in a London borough, the current study shows that social media have polarized gangs, resulting in two distinct types of digital adaptation. The proposed division of ‘digitalist’ and ‘traditionalist’ gangs is rooted in Thrasher’s (1927) dictum that no two gangs are alike and explains how some gangs prefer to keep a low profile, thus, avoiding social media use. ‘Digitalists’, by contrast, prefer to use social media as a way to gain reputation and territorial expansion. They use it to brand themselves and to appear attractive for recruits and customers alike. These differences can be theoretically explained firstly as a generational gap, meaning that younger gang members prefer the use of social media; and secondly, by how well established a gang already is, as newer gangs need more attention to establish themselves.

The effects of neighbourhood characteristics on the development of children and adolescents is a key area of research in the social sciences literature. Early papers such as Brooks-Gunn et al. (1993) document strong associations between children’s outcomes and the characteristics of the neighbourhoods they live in. More recent work finds evidence that the neighbourhood children grow up in a↵ects their earnings, college attendance, marriage, fertility (Chetty et al., 2016; Chetty and Hendren, 2018a,b; Chyn, 2018; Deutscher, 2020), and school performance (˚Aslund et al., 2011; Galster et al., 2016). One particular concern is the e↵ect of neighbourhood characteristics on adolescents’ criminal, delinquent, and health-compromising activities (for a review, see Leventhal and Brooks-Gunn (2000)), in particular the potential negative impacts of gangs, drugs and violence on children and young teenagers (Jencks and Mayer, 1990; Popkin et al., 2002). A small literature investigates the impact of exposure to crime on the criminal behaviour of young men and women, but little is known about which type of criminal activity in the neighbourhood may lead to spillovers, how this compares with the impact other neighbourhood characteristics have on later outcomes, how exposure to crime affects other dimensions of risky behaviour in particular for girls, and what the longer-term economic consequences of exposure to crime for males and females are….

While gangs and gang culture have been around for countless centuries, The Gang is one of the first academic studies of the phenomenon. Originally published in 1927, Frederic Milton Thrasher’s magnum opus offers a profound and careful analysis of hundreds of gangs in Chicago in the early part of the twentieth century. With rich prose and an eye for detail, Thrasher looked specifically at the way in which urban geography shaped gangs, and posited the thesis that neighborhoods in flux were more likely to produce gangs. Moreover, he traced gang culture back to feudal and medieval power systems and linked tribal ethos in other societies to codes of honor and glory found in American gangs

As a steady source of juvenile delinquents and an incubator for future adult offenders, the youth gang has long been a focus of attention, from their origins and prevalence to intervention and prevention strategies. But while delinquent youth form gangs worldwide, youth gang research has generally focused on the U.S.

Youth Gangs in International Perspective provides a needed corrective by offering significant studies from across Europe, as well as Trinidad-Tobago and Israel. The book spans the diversity of the field in the cultural and scholarly traditions represented and methods used, analyzing not only the social processes under which gangs operate and cohere, but also the evolution of the research base, starting with the Eurogang Program’s definition of the term youth gang. Cross-national and gender issues are discussed, as are measurement concerns and the possibility that the American conception of the youth gang is impeding European understanding of these groups.

Every day there are new stories of gang-related crime: from the proliferation of illegal weapons in the streets and children dealing drugs in their schools, to innocent bystanders caught in the crossfire of never-ending gang wars. Once considered an urban phenomenon, gang violence is permeating American life, spreading to the suburbs and bringing the problem closer to home for much of America. The government, schools, social agencies, and the justice system are conspicuous by their sporadic interest in the subject and have failed to develop effective policies and programs. Existing social support mechanisms and strategies for suppressing violence have often been unsuccessful. And, state and federal policy is largely nonexistent.In The Youth Gang Problem: A Community Approach, Irving Spergel provides a systematic analysis of youth gangs in the United States. Based on research, historical and comparative analysis, and agency documents and the author's extensive first-hand experience, the work explores the gang problem from the perspective of community disorganization, especially population movement, and the plight of the underclass. It examines the factors of gang member personality, gang dynamics, criminal organization, and the influence of family, school, prisons, and politics, as well as the response of criminal justice agencies and community groups.

  Spergel describes techniques used by social agencies, schools, employment programs, criminal justice agencies, and grass-roots organizations for dealing with gangs, and recommends strategies that emphasize the use of local resources, planning, and collaborative procedures.There is no single strategy and no easy solution to the youth gang problem in the United States. There are, however, substantial steps we can take, and they must be honestly and systematically tested. Offering a practical and alternative approach to a serious social problem, The Youth Gang Problem: A Community Approach is a major and long-awaited contribution to this dilemma. It is required reading for criminal justice personnel, school staff, social workers, policy makers, students and scholars of urban and organizational sociology, and the general reader concerned with the youth gang problem and how to control, intervene, and prevent it.

Choo explores group delinquency in the Asian American community. His primary focus is two youth groups, a Korean affiliated Chinese youth gang and a Korean delinquent group. The two groups have evolved through different processes and under different community circumstances. Both manifest differing patterns of delinquent activities and require different approaches to their problems. By analyzing the demographic, socioeconomic, and cultural characteristics of the Korean immigrant community, the book discusses the unique lifestyle of Korean-American immigrants in relation to their youth and group delinquency problem. Choo also explains the phenomenon of gangs and immigrant youth by detailed comparison of the emergence, development, persistence and change of theser two distinctive groups.

. In scrutinizing the discourse on ‘gangs’ in media reports and speeches made by politicians, the author demonstrates that the racialization of gun and knife-enabled crime is the consequence of casual labelling. Referring to a speech by Tony Blair in February 2007, in which he uses words ‘black kids’, ‘gangs’, ‘criminal cultures’ and ‘the black community’, the author shows how it effectively ‘serves to collectivize the problem as one specific to, arising from and potentially encompassing, the black community as a whole’. …Targeting gangs and using civil injunctions will perpetuate the problem by drawing more young black people into the justice system. This is happening while the over-representation of young black people in the criminal justice system and experiences of disadvantage and discrimination in other areas remains to be addressed. … There are better ways of dealing with it: involving young people from under-privileged groups in positive activities from an early age, supporting parents with limited resources and supervising and supporting young offenders caught up in the criminal justice system
