While the roots of criminology largely lie in sociological explanations for crime and delinquency, a resurgence has begun wherein human behavior is explained as a product of both environmental and biological factors: biosocial criminology. Biosocial criminology encompasses many perspectives that seek to explain the relationships between human behavior and genes, evolution, neurobiology, and more. While biosocial criminology does not have a long history in the broader field of criminology, modern advances in technology have made access to data to explore biosocial criminological questions far more readily available. Advanced technology, coupled with studies suggesting that a large proportion of the variance in antisocial behavior is attributable to genetic factors has spurred many criminologists to explore how both nature and nurture influence behavior.
A wide variety of perspectives is apparent within biosocial criminology. These perspectives can be seen as tools to uncover different elements of the equation seeking to understand human behavior. Behavior genetic studies seek to explain what proportion of the variation in a trait or behavior is due to genetic factors. Molecular genetic studies seek to uncover which genes are related to that trait or behavior and how strongly they are associated. Evolutionary psychology seeks to explain why a trait or behavior emerged and remained through the process of natural selection. Neurobiological studies explain how the complex structure and function is related to traits and behavior. While these perspectives vary widely in their approach, one fact remains: neither environmental nor biological explanation for human behavior is sufficient on its own; rather, the complex interplay between environments and biology is critical to advance knowledge about the causes and correlates of criminal and delinquent behavior.
The phenomenon of illegal markets is pervasive. The circulation of illegal goods and services reaches all social segments, crosses national boundaries, and produces enormous revenues. Scholarship has typically addressed issues of illegal exchanges by focusing on criminal organizations, their members’ activities, internal structures, and businesses while leaving the very notion of illegal markets conceptually underdeveloped. Different from organized crime, the notion of “illegal market” compels us to consider the demand side and to investigate the varied ways it relates to the supply side. Following the path opened up by economic sociology scholarship, this article brings illegal markets to the center of the scene in order to develop them conceptually, observe them in a differentiated way, and investigate their relationships with legal structures. From this perspective, the social organization of markets comes to the fore, highlighting such aspects as the formal and informal institutions sustaining illegal markets; the modes of internal coordination that deal with problems such as value, competition, or trust; moral attitudes toward the production, exchange, or consumption of certain products or services; the cultural elements or cognitive dispositions that promote illegal exchanges; the role of state power in defining what is and is not illegal, and thus how it controls certain exchanges; and the role of the enforcement of the law in the emergence, expansion, or extinction of these markets.

This article examines the who, what, where, when, why, and how of gang joining. The question of what youth join when they join gangs speaks to the contested nature of gang definitions and types and the consequences of gang membership, specifically heightened levels of offending and victimization. The type of gang and the obligations of membership influence the joining process. Where youth join gangs, namely, the neighborhood and social context, also impacts individual opportunities and preferences for joining. When youth join gangs is considered in a developmental sense, to include both adolescent and adult onset, in order to account for continuity and change in individual levels of immersion or “embeddedness” in gangs across the life course. Who joins gangs provides a profile of gang membership grounded in the well-documented risk factors for gang membership, but limited by problems of prediction. Why youth join gangs speaks to the push and pull factors for membership, the appeal of gangs, and the selective incentives they offer. Still, motivations for gang membership cannot fully explain selection into gangs, nor can general theories of crime that do not necessarily fit with general knowledge of gangs. How youth join gangs, for example, is more complicated than initiation rites. The mechanisms underlying the selection process can be understood through the lens of signaling theory, with implications for practice.

Gang organization has been an aspect of research that is often explored and debated. The concept of organization is intertwined with questions of whether gangs have leaders, whether gangs can be considered organized crime, which groups are actually street gangs, and other related questions. Though there are some crossover categories, street gangs are viewed as distinctly different than organized crime groups, prison gangs, outlaw motorcycle clubs, skinheads, stoners, and taggers.
Gang structures are widely varied, with a few being highly organized and most being loose networks of associates. The organization of a gang may change over time. There is an array of membership types that range from core members who might maintain affiliation well into adulthood to temporary members who only spend a short time in the gang. Gangs may have sub-group clique structures based on age-graded cohorts, neighborhoods, or criminal activity. Leadership roles in gangs rarely take the form of a recognizable figurehead.
These variations have led to a plethora of gang categories that include evolutionary typologies that place gangs by their stage in criminal sophistication, behavioral typologies that identify gangs by the type of criminal behavior the members engage in, and structural typologies that differentiate gangs by the characteristics of their composition. It is important to note that most of the following gang typologies are focused on gangs in the United States and may not be as relevant in other countries.
Major gang affiliations are also explored. Like other aspects of organizations, affiliations are not stable, as gang alliances are volatile. Despite the ability of affiliations to fluctuate, this categorization strategy is commonly used outside of academic research.

Scholarship in criminology has focused on individuals’ pathways to crime—how life experiences, often beginning during childhood, lead to criminality in adolescence or adulthood. General frameworks for this research include life-course, developmental, and biosocial criminology. However, because the vast majority of the general pathways research literature was developed using samples of boys and men, scholars with a feminist theoretical background argue that such research is not truly representative of girls and women’s pathways to crime. While general theories of crime have been applied broadly, gender-specific pathways to crime account for important distinctions between male and female experiences.
Thus, gender (and sex), through biological differences, social norms, and expectations, shapes individual life experiences that result in distinct pathways to crime for men and women. Consequently, understanding criminality requires a full consideration of gendered experiences. Even though similar life events may occur with both men and women, individual responses and effects can vary greatly and lead to different pathways to criminal behavior. Accordingly, this article discusses pathways to crime though a gendered lens. First, men’s pathways to crime are presented, which have been traditionally represented through general criminological research. Next, women’s specific pathways to crime are discussed, developed primarily through the gendered pathways literature. Finally, future directions in pathways research are outlined.
