A national health interview study (NHIS) is a survey that collects information about the health of a population. It is conducted by the National Center for Health Statistics (NCHS) and is the largest health survey in the United States. The NHIS collects data on a variety of health topics, including:
- Health status
- Health care utilization
- Health insurance coverage
- Health behaviors
- Health outcomes
The NHIS is an important source of data for public health researchers and policymakers. It helps to track the health of the population over time and identify trends and disparities. The NHIS also provides data that can be used to evaluate the effectiveness of public health programs.
The NHIS was first conducted in 1957. It has been conducted annually since 1960. The NHIS is conducted using a stratified multistage probability sample design. This design ensures that the sample is representative of the population of the United States.
The NHIS is a valuable resource for public health research and policymaking. It provides data that can be used to track the health of the population, identify trends and disparities, and evaluate the effectiveness of public health programs.

This information can be used to identify emerging health problems and develop targeted interventions to address them. For example, the NHIS data has been used to track the decline in smoking rates in the United States over the past several decades.
- Identifying Disparities: The NHIS data can also be used to identify disparities in health between different population groups. For example, the NHIS data has been used to show that racial and ethnic minorities are more likely to experience chronic health conditions and have less access to health care than white Americans.
- Evaluating Programs: The NHIS data can be used to evaluate the effectiveness of public health programs. For example, the NHIS data has been used to evaluate the impact of the Affordable Care Act on health insurance coverage and access to care.
The longitudinal nature of the NHIS makes it a valuable resource for public health research and policymaking. The NHIS data can be used to track trends in health over time, identify disparities in health, and evaluate the effectiveness of public health programs.
Representative
The National Health Interview Survey (NHIS) is a nationally representative survey of the civilian, noninstitutionalized population of the United States. This means that the NHIS data can be used to make inferences about the health of the entire U.S. population, including subgroups of the population, such as racial and ethnic minorities, children, and the elderly.
- Stratified sampling: The NHIS uses a stratified sampling design to ensure that the sample is representative of the U.S. population. This means that the population is divided into strata, such as age, race, and gender, and then a sample is selected from each stratum.
- Multistage sampling: The NHIS uses a multistage sampling design to select the sample. This means that the population is divided into stages, such as counties, census tracts, and households, and then a sample is selected from each stage.
- Probability sampling: The NHIS uses a probability sampling design to select the sample. This means that every member of the population has a known chance of being selected for the sample.
The stratified multistage probability sample design of the NHIS ensures that the sample is representative of the U.S. population. This makes the NHIS data a valuable resource for public health researchers and policymakers.
