National Health Interview Survey

The National Health Interview Survey (NHIS) is the principal source of information on the health of the civilian noninstitutionalized population of the United States and is one of the major data collection programs of the National Center for Health Statistics (NCHS). The NCHS is part of the Centers for Disease Control and Prevention (CDC).

You can find both a brief fact sheet and a comprehensive description of the survey, including its purpose and scope, sample design, questionnaire content, and data collection procedures, on the CDC Web site.

The NHIS Core and Supplements

Each year, the NHIS includes a set of basic health and demographic items, called the Core questionnaire, plus additional sets of questions on current health topics, called Supplements.
