Victimizations and incidents are classified based on detailed characteristics of the event provided by the respondent. Neither victims nor interviewers classify crimes at the time of interview. During data processing, a computer program classifies each event into one type of crime, based on the entries on a number of items on the survey questionnaire. This ensures that similar events will be classified using a standard procedure. The glossary definition for each crime indicates the major characteristics required to be so classified. If an event can be classified as more than one type of crime, a hierarchy is used that classifies the crime according to the most serious event that occurred. The hierarchy is rape, sexual assault, robbery, assault, burglary, motor vehicle theft, and theft. (https://www.bjs.gov/index.cfm?ty=tda)
