National Health Interview Survey - Child


The National Health Interview Survey (NHIS) is a national household interview survey that has been conducted continuously since 1957, and is administered by the Centers for Disease Control and Prevention's (CDC) National Center for Health Statistics (NCHS). The NHIS provides a broad range of information about the health status of the US civilian non-institutionalized household population including all adults and children in the family.

Since 1997, the NHIS questionnaire has consisted of a Core and variable supplements. The Core consists of four components: The Household Composition, the Family Core, the Sample Adult Core, and the Sample Child Core. The Household Composition section collects information about basic demographic characteristics of all persons in the household. The Family Core component collects information about socio-demographic characteristics, health, activity limitations, injuries, health insurance coverage, use of and access to health care services for all persons in the family. The Sample Adult and the Sample Child Cores obtain additional information on health status, health care services, and behavior for a randomly selected adult or child, ages 0 to 17 years old, from each family.

Fast-track your use of NHIS-Child data:

The Data Resource Center (DRC) takes the sample child-level data from the NHIS Sample Child, Household Composition and Family components and makes the results easily accessible to parents, researchers, community health providers and anyone interested in child health data. The DRC provides estimates on children’s health, health care, and family resources that are nationally representative. State level estimates are available from the pooled year of datasets. Both national and state level (where sample size permits) data can be further refined to assess differences by race/ethnicity, income, and a variety of other important demographic and health status characteristics.
