National Health Interview Survey (NHIS)
Back to all collectionsSummary
The National Health Interview Survey (NHIS), conducted by the CDC's National Center for Health Statistics (NCHS), is the nation’s largest and longest-running health survey, monitoring the health of the U.S. population since 1957. NHIS collects and analyzes data on a wide range of health topics, with a focus on both adults and children. Each year, approximately 27,000 adults participate in confidential, face-to-face interviews, often providing health information about children in their households.
