National Health Interview Survey

Alternate Titles(s): NHIS

UID: 10004

The National Health Interview Survey is a cross-sectional household interview survey. Sampling and interviewing are continuous throughout each year. The sampling plan follows a multistage area probability design that permits the representative sampling of households and noninstitutional group quarters (e.g., college dormitories). NHIS addresses topics such as health status, use of health services, health behaviors, insurance coverage, access to care, measure of functioning, injuries and poisonings, immunizations, and conditions (e.g. asthma, diabetes, heart, mental health, cancer).
