Historically, criminological theories have aimed to explain criminal propensity, providing explanations for why some individuals are more likely than others to commit an offense. Conversely, less attention has been paid to the other element of a crime event: opportunity. This trend was radically altered from the 1970s onward, in large part due to Lawrence Cohen and Marcus Felson’s creation of a “routine activity approach” to understanding crime trends. The scholars proposed that, beyond the necessity of a motivated offender, crimes occur when suitable targets are present and capable guardians are absent. The contribution of routine activity theory increased interest in the role of criminal opportunity substantially, with various streams of research coalescing into a school of criminological thought known as “environmental criminology,” sometimes referred to as “crime science.” Routine activity theory is central to these approaches and is focused on crime reduction through the prevention and control of chances to commit crime.
Routine activity theory was initially proposed as a sociological perspective, as Cohen and Felson explored aggregate associations between social trends (such as sociodemographic changes in household activity and urbanization) and the risk of victimization. Their analyses suggested that as changes occurred in the routine activities of Americans post-World War II, crime rates increased. From this original conceptualization, routine activity theory has evolved into the “crime triangle,” which provides a way of analyzing crime problems. The triangle depicts that crime events occur when motivated offenders and attractive targets converge in space and time in the absence of guardianship. Research has further specified that three crime control actions paired with these elements—handling for offenders, guarding for targets, and managing for places—can reduce crime events. There are now hundreds of studies that examine the relationship between routine activities and crime, with many of these empirical investigations organized around the crime triangle. Theoretical advancements have outlined the role of targets and guardians, the levels of responsibility of crime controllers, the attractiveness of targets, the characteristics of (in)effective guardianship, and the social processes related to the presence or absence of handlers, guardians, and managers. Considering the combined contributions of this canon of literature, the evidence is clear in demonstrating the utility of routine activity theory for understanding and preventing crime.
