The National Health Interview Survey

The National Health Interview Survey (NHIS) is a large-scale, ongoing government research project that gathers information directly from individuals about their health, healthcare access, and health-related behaviors. Conducted through face-to-face or phone interviews, it helps identify health trends, monitor disease prevalence, and inform public health policies. The survey covers topics like chronic conditions, lifestyle choices, and health insurance. By collecting this data nationally, NHIS provides a comprehensive picture of the health status of the U.S. population, aiding policymakers, healthcare providers, and researchers in making informed decisions to improve public health.
