On November 2nd 2006, 54 out of 121 identified local domestic violence programs (45%) in California participated in the National Census of Domestic Violence Services (NCDVS). Designed to address the safety and confidentiality needs of victims, the Census collected an unduplicated, non-invasive count of adults and children who received critical services from local domestic violence programs during the 24-hour survey period. Since some local programs did not participate, this Census provides a powerful glimpse but remains an undercount of the actual number of victims who sought and received services.
