About the redesign

The National Crime Victimization Survey (NCVS) is one of two Justice Department measures of crime in the United States. A pioneering effort when it was begun in 1972, the survey was redesigned and the new methodology was systematically field tested and introduced starting in 1989. The first annual results from the redesigned survey were published for 1993.

Why redesign?

Criticism of the earlier survey's capacity to gather information about certain crimes, including sexual assaults and domestic violence, prompted numerous improvements.

Improved survey methodology improves the ability of people being interviewed to recall events.

Public attitudes toward victims have changed, permitting more direct questioning about sexual assaults.

What is the redesign?

An advisory panel of criminal justice policymakers, social scientists, victim advocates, and statisticians oversaw the work of a consortium of criminologists and social and survey scientists who conducted research on improved procedures.

New questions were added to accommodate heightened interest in certain types of victimizations. Improvements in technology and survey methods were incorporated in the redesign. The survey now includes improved questions and cues that aid victims in recalling victimizations. Survey interviewers now ask more explicit questions about sexual victimizations. Advocates have also encouraged victims to talk more openly about their experiences. Together, these changes substantially improve reporting for many types of personal and household crime.

What are the results of the redesign?

Victims are now reporting more types of crime incidents to the survey's interviewers. Previously undetected victimizations are being captured. For example, the survey changes have substantially increased the number of rapes and aggravated and simple assaults reported to interviewers. For the first time, other victimizations, such as non-rape sexual assault and unwanted or coerced sexual contact that involves a threat or attempt to harm, are also being measured.
