A study on how the relatively poor residents of Comuna 13, especially young people, have adapted to changing socio‐economic conditions since the Colombian government reasserted control over the Medellín neighborhood after Operation Orión in 2002.

The present study evaluates adolescent victimization and offending using cross-sectional survey data from 1,475 adolescents living in a disadvantaged Comuna in Medellin, Colombia, while paying particular attention to the ways in which both victimization and violent offending are operationalized. We find that 37% of respondents experienced no lifetime victimization, while 60% experienced vicarious, and 4% personal victimization. When restricting violent offending to behavior involving a weapon, the majority of offenders (81%) also experienced victimization while only 33% of victims were also weapons offenders. Our final analysis seeks to identify theoretical conditions which differentiate roles in a victim-offender typology, a result we determine varies significantly depending on how "violent offending" is measured.

The present study evaluates adolescent gang involvement using crosssectional survey data from 1,475 adolescents living in a disadvantaged Comuna in Medellin, Colombia. Specifically, we examine the prevalence of former and current gang membership, affiliation with gang members, and lives untouched by any gang association. Once these groups are established, we identify variation in membership on the basis of demographic and theoretical variables, and determine whether such variation can be described by using the selection, facilitation, and enhancement models developed by Thornberry et al. While our results, consistent with many prior findings using North American samples, support the selection model for most theoretical variables and enhancement for behavioral outcomes, our strongest contribution is our study's ability to demonstrate the temporal impact of gang involvement.
