What type of information does self-report data generally seek?

Self-report data primarily seeks to gather personal information about individuals' experiences and behaviors related to crime, which often includes whether they have been victims of crime. This type of data collection allows researchers to obtain firsthand accounts from individuals about their experiences with criminal acts, the nature of those experiences, and other relevant details that might not otherwise be captured through official crime statistics or reports.

In criminology, self-report surveys can provide valuable insights into the prevalence of victimization, assisting in understanding patterns of crime from the perspective of those directly affected. This contrasts with the other options, which focus on different aspects of crime. Demographic details pertain to offenders rather than victims; police interventions concern law enforcement measures rather than personal experiences; and public opinions give insight into societal perceptions, which do not reflect individual victimization experiences directly. Thus, the correct answer accurately represents the primary focus of self-report data in criminological research.
