1 Foundations of Criminology
Learn how criminology defines and studies crime, compares explanations of offending, and evaluates social control and responses to crime.

examines , criminal behavior, victimization, and the social responses to . It is interdisciplinary, drawing on fields such as sociology, psychology, economics, political science, and law. Criminologists investigate questions about conditions that influence offending, the effects of laws and institutions on behavior, and the effectiveness of prevention and punishment.

In law, a is conduct prohibited by a jurisdiction’s criminal law and subject to formal punishment. What counts as a depends on the law in force, which can differ across places and change over time.
is conduct that violates social expectations. It is not the same as : some deviant acts are legal, and some crimes may not be widely viewed as immoral. The distinction is between conduct defined by social norms and conduct prohibited by criminal law.
How criminologists study
Criminologists use theories to organize observations and explain patterns. A theory should make clear, testable claims that researchers can compare with evidence.
Researchers may draw on official records, surveys, interviews, observations, experiments, and comparisons across communities or time periods. Each method has limits. Police records count offenses reported to and recorded by law enforcement, whereas victimization surveys can capture some offenses that are not reported to police. These sources answer different questions, so no single statistic represents every aspect of .
Researchers distinguish from . If neighborhood disadvantage and recorded occur together, that observation alone does not show that one causes the other. Researchers consider alternative explanations, define concepts carefully, and examine how data were collected.
Major approaches to explaining
Criminological perspectives often emphasize different levels of explanation. They can complement one another rather than provide mutually exclusive answers.
Choice and approaches examine decisions and opportunities, including how perceived risks, rewards, and circumstances may affect behavior. distinguishes the effect on a person punished for an offense from the effect a threatened sanction may have on others.
Biological and psychological approaches examine individual differences and development, including how psychological processes or traits may relate to behavior. These factors are studied in context and do not by themselves determine that a person will offend.
Social learning approaches propose that behavior and attitudes favorable to offending may be learned through interaction with others. For example, close associates may teach a person techniques and justifications for fraud.
Strain approaches examine pressure arising when people face obstacles to socially valued goals or experience other sources of strain. They consider how circumstances and available coping options may shape responses; strain does not make inevitable.
Social disorganization approaches focus on community conditions and local capacity for collective support and informal . They examine how instability, concentrated disadvantage, and weakened social ties can affect a community’s ability to address problems together.
approaches ask why most people conform to rules. They emphasize bonds to family, school, work, and community, as well as commitments and beliefs that may discourage offending.
Labeling approaches study how social reactions and official labels can affect a person’s identity, opportunities, and later behavior. They consider not only why an act occurred but also how authorities and communities respond.
Conflict and critical approaches examine how power and inequality influence the creation and enforcement of laws, which harms receive attention, and how justice systems affect different groups.
For repeated shoplifting, one researcher might examine opportunity and perceived risk, while another might study peer learning, economic strain, or ties to school and family. A fuller account may consider several factors and how they interact.
and responses to
refers to how societies encourage conformity and respond to rule-breaking. Informal includes guidance from family or community; formal includes laws and sanctions administered by justice institutions.
studies more than offending. It also examines how laws are made, how policing and courts operate, how punishment is justified, and how responses affect victims, people who offend, and communities.
Punishment may be intended to express accountability, deter future offending, prevent further harm through confinement, or support rehabilitation. These are distinct goals. A policy’s intended purpose does not establish that it achieves that outcome, so criminologists evaluate claims about policing and punishment against evidence while considering fairness, effectiveness, and possible unintended consequences.
