The National Crime Victimization Survey (NCVS) is a household-based demographic survey that yields annual national estimates of property crime and nonfatal violent crime, both reported and not reported to the police. Interviews are conducted year-round by Census Bureau Field Representatives (FRs) through personal visit or by telephone, using a Computer-Assisted Personal Interview (CAPI) instrument. In sampled households, persons of age 12 and older are given screener interviews to determine if they have been victimized during the previous six months. If a crime is reported during the screener, the interview continues with an incident report to ascertain details of the event.
