Measuring Crime Statistics
When attempting to understand, predict, and control any social problem, including the crime problem, the first step is to determine its extent.
Three categories of major crime data sources in the United States:
Victimization survey data
Uniform Crime Reports (UCR) - collected by local police departments and forwarded to the FBI.
– good or bad?
- NIBRS - “new” – what is it? – good or bad?
National Crime Victimization Surveys (NCVS) - conducted jointly by the U.S. Census Bureau and the U.S. Department of Justice.
- good or bad
Self-Report Data (SRD) - conducted by independent researchers.
- good or bad?
Part I (Index Crimes)
Motor vehicle theft
Part I offenses include those illegal acts considered to be particularly serious that “occur with sufficient frequency to provide an adequate basis for comparison” (U.S. Department of Justice, 1980:3)
Part II (Non-Index Crimes)
Part II offenses include most other crimes not itemized in Part I. Twenty specific crimes and a catchall “other” category are in this section, including other assaults, embezzlement, vandalism, sex offenses, drunkenness, and status offenses. (reporting only includes cries that are cleared by an arrest)
