Statistics In-Depth

NSVRC does not conduct research, but we share research from a variety of sources including government entities such as the Centers for Disease Control and Prevention (CDC) and the U.S. Department of Justice, Bureau of Justice Statistics (BJS). We also share research studies conducted by reputable researchers and institutions throughout the country.

Measuring the scope, impact, and prevalence of sexual assault, harassment, and abuse can be difficult. No single source of data provides a full picture. We rely on the two largest national data collections that gather information on sexual violence, the National Intimate Partner and Sexual Violence Study (NISVS) and the National Crime Victimization Survey (NCVS).

These large data collections are complemented by smaller-scale studies conducted by researchers affiliated with institutions throughout the country. They can offer additional insight and information on the scope of sexual assault. The past decade of research in particular has shown the numerous contexts and impacts that sexual assault, harassment, and abuse play in the lives of individuals and communities.

Research provides the opportunities to better understand the experiences of victims. Ultimately data can help inform successful prevention strategies based on the lived experiences of individuals and communities.

Keep in mind when comparing studies that data — such as prevalence rates — published in one study may not immediately appear to correspond to rates found in a different study. This alone doesn’t mean either study is wrong. At the beginning of every study, researchers make decisions around several key issues that will affect the ultimate results of their study. These often include:

Decisions on what gets recorded, who gets asked, how they are asked, etc. all impact the final outcomes of any study. Attempting to compare studies that use different definitions and behaviors, population samples, and other distinctions could provide inaccurate conclusions or judgements.

About Primary Sources

The primary sources we rely on for data on sexual violence victimization are:

The National Intimate Partner and Sexual Violence Survey (NISVS). The National Intimate Partner and Sexual Violence Survey is the primary source NSVRC relies on for sexual victimization information. NISVS was launched in 2010 by the National Center for Injury Prevention and Control (U.S. Centers for Disease Control and Prevention). NISVS is an ongoing nationally representative survey that collects data on adult men and women at the national and state level. The goals of NISVS are to collect detailed information about sexual violence, physical violence by an intimate partner, and stalking. The initial, and largest, collection of NISVS data took place in 2010. From this data collection, additional analyses on specific population groups were released in subsequent years.

The National Crime Victimization Survey (NCVS) is based on data gathered by the U.S. Department of Justice. This is also a national, randomly chosen survey of households. Respondents are asked about the number and characteristics of all crimes they have experienced during the past six months. This includes rape and sexual assault, robbery, assault, domestic violence, crime involving injuries, and others.
