Census Methodology & Understanding the Data
Domestic Violence Counts 2013: National Census of Domestic Violence Services (Census)
The Domestic Violence Counts survey provides a point-in-time, noninvasive, unduplicated record of individuals who access domestic violence services during a single 24-hour period. Developed in 2006 by a team of experts in the field of domestic violence, the goal of the survey is to count the number of individuals who contact domestic violence programs in search of assistance.
The “snapshot” methodology provides an unduplicated count because a victim is unlikely to access services at more than one domestic violence program during a 24-hour period. It is impossible for a victim to be sheltered in two programs at the same time, and it is unlikely that a victim will travel from one primary purpose domestic violence program to another in the same day. Programs are often located far apart and serve wide geographic areas.
The Domestic Violence Counts survey is noninvasive and takes into account the dangerous nature of domestic violence and the need to prioritize victim safety and confidentiality. The report is an aggregate nationwide (and statewide) count of victims who seek services and an aggregate count of services programs provide.
Understanding the Data
Does this mean that over 65,000 people were victims of domestic violence on the day of count?
- No. Because we survey only domestic violence programs, the survey doesn’t count how many people were victims of domestic violence on the designated day. It records how many people sought services from domestic violence programs on September 17, 2013. We don’t know, definitively, how many victims of domestic violence there are on any given day because not all victims seek services immediately after experiencing abuse.
Can we extrapolate and project what the numbers served would be if 100% of local programs participated in the Census count?
- No. With an 87% response rate, it is not possible to extrapolate since the 13% of programs that did not participate may have been the smallest, least staffed programs, or they could be extremely large and overly busy programs. Extrapolating the current data to project or estimate a total number of victims seeking services on this day would likely produce an inaccurate total count. Any attempt at extrapolation or projection would require a much closer analysis of nonparticipating programs than this study intends or attempts to make.
This count was only on one day. Can I multiply it by 365 and get an average estimate of the number of victims who sought services in a year?
- No. The Domestic Violence Counts report provides an unduplicated count of victims who seek services in just one day. Throughout the year, some victims might only use services once a year, while others may access support many times over the course of a year. In addition, most programs experience days when many victims seek services and some days when few victims seek services. Thus multiplying the 1-day total by 365 to create an annual number would be inaccurate.
Why can’t you just do an annual unduplicated count?
- Getting an annual unduplicated annual count is impossible because you’d have to make sure you’re not counting the same person twice. In order to do so, domestic violence programs would need to collect in-depth personally identifying information about victims and share that information with other domestic violence programs. This disclosure would be a violation of federal law and many state laws. In addition, victims of domestic violence often suffer from abusers who believe it is their right to control and monitor them. Because we respect survivors’ privacy, confidentiality, safety, and dignity, we will not do so.
