The NCVS measures criminal victimization and victim help-seeking behaviors in the United States. As the nations primary source of data on crimes reported and not reported to police, the NCVS collects information on nonfatal violent and property crimes from a nationally representative sample of persons age 12 or older in U.S. households. In addition to the core collection, the NCVS survey operation also produces data on stalking, identity theft, fraud, school crime, and contact between police and the public. Since the inception of the survey in 1973, BJS has endeavored to maintain and enhance the quality and relevance of estimates produced from this important yet complex survey. As part of recent efforts to promote the quality and relevance of NCVS and related estimates, BJS has maintained an active research and development program in several areas including an effort to explore options for redesign of the NCVS instrument, development of subnational victimization estimates, improvement of hate crime and identity theft measures, and data collection on victim services providers. The primary objective of the NVSSP is to support ongoing statistical and methodological research to enhance the utility and efficiency of BJSs $52 million NCVS, including informing the NCVS survey redesign research and BJSs decisions about various aspects of its victimization statistics program.
