Several conclusions were drawn from the report. First, current national data collection efforts cover portions of these four categories of crime (domestic violence, dating violence, sexual assault and stalking) among different segments of the victim population. Because the efforts use different definitions and vary in scope, they cannot be combined and leveraged to determine nationwide prevalence of these categories of crime. Second, the absence of comprehensive nationwide prevalence information somewhat limits the ability to make informed policy and resource allocation decisions about the statutory requirements and programs created to help address these crimes and victims. Third, the U.S. Department of Justice and Health and Human Services have collaborated to obtain more uniformity across research efforts and have initiatives in the early stages that could be used to collect information on prevalence. Fourth, the U.S. Department of Justice and Health and Human Services must determine to what extent they can cost-effectively revise current efforts or design new initiatives in order to collect more consistent data. Lastly, policymakers need to decide whether it is worth the cost to obtain better data. This decision should be based on judgments about marginal costs, utility of better data, benefits derived from the better data, and availability of funds to gather data. Recommendations in relation to these conclusions are presented and discussed. In hearings conducted between 1990 and 1994, the U.S. Congress noted that violence against women was a problem of national scope and that the majority of crimes associated with domestic violence, sexual assault, and stalking were perpetrated against women.
