  • Multiple Cause of Death or Mortality File
    This is a portal to the online data dissemination activities of the Division of Vital Statistics, including both interactive online data access tools and downloadable public use data files. Data related to child abuse deaths can be queried using these tools.
  • National Health Interview Survey Injury Section (NHIS)
    The NHIS has monitored the health of the nation since 1957. NHIS data on a broad range of health topics are collected through personal household interviews. Recent survey years include data on adverse experiences like neighborhood violence, parental incarceration, household mental illness or substance use, food insecurity, and poverty.
  • National Hospital Ambulatory Medical Care Survey (NHAMCS)
    NHAMCS collects data on the use and provision of ambulatory care services in hospital emergency and outpatient departments and ambulatory surgery locations. Some years include the International Classification of Diseases (ICD) reason for visit code, which can be used to look at child abuse and neglect.
