National Health Interview Survey Early Release Program

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.


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.
