Victimisation, in sociology and criminology, refers to the process or experience of being a victim of crime, injustice, or other harmful social phenomena. This category encompasses various aspects related to the victim's perspective and their interactions with the criminal justice system and society. It includes the study of victimisation surveys, which collect data directly from individuals about their experiences as victims of crime, regardless of whether the crime was reported to the police. It also delves into the concept of victimless crimes, where there is no direct complainant, and examines the social and psychological impacts of being a victim of crime or other forms of harm, such as hate crimes, domestic violence, or discrimination. The study of victimisation also considers victimology, which is the scientific study of victims, and explores patterns of victimisation, risk factors, and the role of victims in the criminal justice process and in society's response to crime and harm.
