National Child Abuse and Neglect Data System
The National Child Abuse and Neglect Data System (NCANDS) is a federally-sponsored national data collection effort for the purpose of tracking the volume and nature of child maltreatment reported each year within the U.S.
NCANDS case-level data are collected from states through the Child File data submission. States that submit a Child File also submit an Agency File, which collects state-level data for areas not covered in the Child file (e.g., preventive services and screened-out referrals). Child File data are aggregated to the state level by key variables and then combined with data from the Agency File to create the Combined Aggregate File, which is available for analysis.
