The National Health Interview Survey (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. For over 50 years, the US Census
Bureau has been the data collection agent for the National Health Interview
Survey. Survey results have been instrumental in providing data to track
health status, health care access, and progress toward achieving national
health objectives.
