NCVS meaning in Governmental ?

The National Crime Victimization Survey (NCVS), administered by the US Census Bureau under the Department of Commerce, is a national survey of approximately 49,000 to 77,400 households twice a year in the United States, on the frequency of crime victimization, as well as characteristics and consequences of victimization. The survey focuses on gathering information on the following crimes: assault, burglary, larceny, motor vehicle theft, rape, and robbery. The survey results are used for the purposes of building a crime index. It has been used in comparison with the Uniform Crime Reports and the National Incident-Based Reporting System to assess the dark figure of crime. The NCVS survey is comparable to the British Crime Survey conducted in the United Kingdom.

The NCVS began in 1972 and was developed from work done by the National Opinion Research Center and the President's Commission on Law Enforcement and Administration of Justice. A key finding of the survey was the realization that many crimes were not reported to the police.
