The National Network to End Domestic Violence's Domestic Violence Counts: National Census of Domestic Violence Services (Census) is an annual noninvasive, unduplicated count of adults and children who seek services from U.S. domestic violence shelter programs during a single 24-hour survey period. Conducted annually by NNEDV since 2006, this Census takes into account the dangerous nature of domestic violence by using a survey designed to protect the confidentiality and safety of victims.
Data is available for the entire U.S. including territories, or by state, both in English and in Spanish.
