Welcome to the NIS-4

The National Incidence Study (NIS) is a congressionally mandated, periodic research effort to assess the incidence of child abuse and neglect in the United States. The NIS gathers information from multiple sources to estimate the number of children who are abused or neglected, providing information about the nature and severity of the maltreatment, the characteristics of the children, perpetrators, and families, and the extent of changes in the incidence or distribution of child maltreatment since the time of the last national incidence study.

For additional information about the NIS-4, click on the NIS-4 Description and FAQ tabs at the top of the page.
