• The National Crime Victimization Survey (NCVS) an ongoing survey of households since 1973, interviews about 80,000 persons age 12 and older in 43,000 households twice each year about their victimizations from crime. The survey reports on rape, sexual assault, robbery, both simple and aggravated assault, theft, household burglary, and motor vehicle theft and includes those crimes not reported to the police.

• The Uniform Crime Reports (UCR) collects information on crimes reported to law enforcement authorities by victims and voluntarily submitted by the agencies to the FBI. The offenses included are homicide, forcible rape, robbery, aggravated assault, burglary, larceny-theft, motor vehicle theft, and arson. The UCR also collects reports of arrests by law enforcement agencies for the offenses listed above as well as 21 additional offenses.

Further information on these two data sources on crime can be found in The Nation's Two Crime Measures which describes the purposes and advantages of the UCR and the NCVS.
