The National Crime Victimization Survey (NCVS) series, previously called the National Crime Survey (NCS), has been collecting data on personal and household victimization since 1973. An ongoing survey of a nationally representative sample of residential addresses, the NCVS is the primary source of information on the characteristics of criminal victimization and on the number and types of crimes not reported to law enforcement authorities. It provides the largest national forum for victims to describe the impact of crime and characteristics of violent offenders. Twice each year, data are obtained from a nationally representative sample of roughly 49,000 households comprising about 100,000 persons on the frequency, characteristics, and consequences of criminal victimization in the United States. The survey is administered by the U.S. Census Bureau (under the U.S. Department of Commerce) on behalf of the Bureau of Justice Statistics (under the U.S. Department of Justice).

The NCVS was designed with four primary objectives: (1) to develop detailed information about the victims and consequences of crime, (2) to estimate the number and types of crimes not reported to the police, (3) to provide uniform measures of selected types of crimes, and (4) to permit comparisons over time and types of areas. The survey categorizes crimes as "personal" or "property." Personal crimes cover rape and sexual attack, robbery, aggravated and simple assault, and purse-snatching/pocket-picking, while property crimes cover burglary, theft, motor vehicle theft, and vandalism. The data from the NCVS survey are particularly useful for calculating crime rates, both aggregated and disaggregated, and for determining changes in crime rates from year to year.
