National Health Interview Survey Early Release Program
The first 2019 NHIS Early Release estimates will be available in early 2020.
The Early Release (ER) Program of the National Health Interview Survey (NHIS) provides estimates, analytic reports, and preliminary microdata files on an expedited schedule. NHIS data users can have access to these very timely estimates, reports, and microdata files without having to wait for the release of the final annual NHIS microdata files by selected demographic characteristics.
Below are descriptions of and links to each type of ER product.
- Selected Estimates Based on Data from the National Health Interview Survey

- Health Insurance Coverage: Estimates from the National Health Interview Survey

- Wireless Substitution: Estimates from the National Health Interview Survey

Selected NHIS variables are made available via the NCHS Research Data Center with each ER product release. Analysts wishing to use the files should follow standard procedures for using the RDC. Note that NCHS has RDC locations in Hyattsville, Maryland and Atlanta, Georgia, and NCHS data can also be accessed at Census Bureau RDCs and through remote access. See NCHS Research Data Center.
From 2012-2017, the ER program released a series of reports and tabulations on health care access and utilization topics on an as needed basis. Some of these reports or tabulations are also available at Responses to Recent Health Policy Data Requests.
