NDACAN’s primary goals are to support the research of child maltreatment scholars and to promote secondary data analysis as a critical tool for the advancement of scientific understanding. NDACAN activities include acquiring and processing child maltreatment data for dissemination, providing technical assistance to data users, and conducting workshops and institutes regarding the process of secondary analysis.

NDACAN houses a range of different types of datasets from national surveys, large-scale longitudinal surveys, state administrative data, and data collected by individual investigators.

NDACAN’s holdings include:

  • Adoption and Foster Care Analysis and Reporting System (AFCARS)
  • Longitudinal Studies of Child Abuse and Neglect (LONGSCAN)
  • National Child Abuse and Neglect Data System (NCANDS)
  • National Incidence Studies on Child Abuse and Neglect (NIS)
