What can street gangs tell us about radicalization and extremist groups? At first glance, these two groups seem to push the boundaries of comparison. In this article, we examine the important similarities and differences across criminal, deviant, and extremist groups. Drawing from research on street gangs, this article explores issues such as levels of explanation,organizational structure, group process, and the

ABSTRACT The recent development of two paradigms in the social sciences, social capital and the life-course perspective, has proven influential. Though these paradigms overlap, limited research has examined the accumulation of capital over the life-course. In this chapter, we consider the confluence of these paradigms in the context of gang membership; specifically how the onset, continuity, and desistance from gang membership influence the loss and formation of social capital. In addition, the emerging role of technology on the maintenance and creation of social capital for gang members is examined. Lastly, directions for future research explicitly examining social capital in the context of antisocial groups are presented.

This study determined the frequency, prevalence, and turnover in gang membership between ages 5 and 17 years in the United States. Data were from the National Longitudinal Survey of Youth 1997, which is representative of youth born between 1980 and 1984. Age-specific patterns of gang joining, participation, and leaving are estimated based on youths (N = 7,335) self-reported gang membership at the baseline and eight subsequent interviews, which were combined with population age estimates from the 2010 U.S. Census to produce national estimates of gang membership. Sampling variance-adjusted bounds were estimated based on assumptions about missing cases and survey design effects. Demographic and socioeconomic variables are used to compare differences between gang and nongang youth. Youth gang members were disproportionately male, black, Hispanic, from single-parent households, and families living below the poverty level. We estimated that there were 1,059,000 youth gang members in the United States in 2010 (bounds ranging from 675,000 to 1,535,000). The prevalence of youth gang membership was 2.0% (1.2%-2.8%), peaking at age 14 years at 5.0% (3.9%-6.0%). Annually, 401,000 (204,000-639,000) juveniles join gangs and 378,000 (199,000-599,000) exit gangs, with a turnover rate of 36%. We discovered that significantly more people are involved with gangs than previous estimates would suggest. Clinicians and policy makers must recognize that youth gang members may not conform to popular perceptions of gang demographics. The patterns of youth gang membership observed in this study support prevention programs aimed at children before the teen years. This strategy is more likely to succeed than gang intervention or suppression strategies aimed at teens.

A large body of social science literature has focused on the factors that influence sentencing outcomes within the federal court system. A neglected variable in this line of research is the citizenship status of the offender. Using the United States Sentencing Commission’s Monitoring of Federal Criminal Sentences data from 2006, the present study examines the effect of citizenship status on the likelihood of incarceration and the length of the prison sentence. This study extends previous research in three ways: first, by examining citizenship status using post-Booker data; second, exploring the differences between citizens, legal aliens, and illegal aliens rather than comparing all non-citizens to US citizens; and third, examining all offenses rather than only drug offenses. Most importantly, this study partitions the data by citizenship status to determine if the effects of race/ethnicity and other variables (e.g., type of offense and level of education) vary by citizenship status. The results demonstrate that both legal and illegal aliens have a higher probability of incarceration than similarly-situated US citizens, but that the sentences imposed on illegal aliens are shorter than those imposed on citizens. However, different results emerged when the data were partitioned by citizenship status. Judges imposed shorter prison sentences on Latino citizens, but longer prison sentences on Latino illegal aliens. These results are discussed in relation to theoretical explanations and policy implications.

Objectives. Drawing from social network and life-course frameworks, the authors extend Hagan's concept of criminal embeddedness to embeddedness within gangs. This study explores the relationship between embeddedness in a gang, a type of deviant network, and desistance from gang membership. Method. Data were gathered over a five-year period from 226 adjudicated youth reporting gang membership at the baseline interview. An item response theory model is used to construct gang embeddedness. The authors estimate a ...

Research on the effects of gang membership on offending has been guided by Thornberry et al.'s (1993) framework of selection, facilitation and enhancement, which correspond to a “kinds of persons” explanation, a “kinds of groups” explanation, and a mix of the two. Krohn and Thornberry (2008) recently summarized the research in this area, concluding that evidence in favor of facilitation effects exceeded that of selection effects. Using a recent longitudinal survey of adjudicated youth, we assess the effect of both gang ...
