“Four federal agencies—the Departments of Defense, Education, Health and Human Services (HHS), and Justice (DOJ)—manage at least 10 efforts to collect data on sexual violence, which differ in target population, terminology, measurements, and methodology. Some of these data collection efforts focus on a specific population that the agency serves—for example, the incarcerated population—while others include information from the general population. These data collection efforts use 23 different terms to describe sexual violence. Data collection efforts also differ in how they categorize particular acts of sexual violence. For example, the same act of sexual violence could be categorized by one data collection effort as “rape,” whereas it could be categorized by other efforts as “assault-sexual” or “nonconsensual sexual acts,” among other terms. In addition, five data collection efforts—overseen by Education, HHS, and DOJ—reflect inconsistencies between their measurements and definitions of sexual violence. Further, these data collection efforts do not have publicly-available descriptions of what is included in their respective measurements to allow persons using the data to understand the differences, which may lead to confusion for data users. Publicly-available measurement information could enhance the clarity and transparency of sexual violence data. Data collection efforts also differ in terms of the context in which data are collected, data sources, units of measurement, and time frames…”
