Community Health Survey Public Use Data

Datasets are available on this page for each year of the Community Health Survey (CHS). For more information on the CHS, visit our Methodology page.

Before downloading any datasets, review the following information:

• Due to the complex sampling design of the CHS, data must be analyzed in a software program capable of handling complex survey data (such as SUDAAN or STATA). Annotated sample code for analysis using SAS and SUDAAN is provided for each year below. Code in SAS without SUDAAN (SAS), as well as code in R (R), are also available.


• A question matrix (PDF) shows which topics are available each year.


• Some conditions may be rare or the sample sizes for some populations quite small, making CHS estimates potentially unreliable. Organizations have various guidelines for when an estimate should be considered unreliable. The Health Department's suggested guidelines for CHS data reliability (PDF) incorporate relative standard error (RSE), confidence interval width, and sample size.


• If an analysis requires the combination of multiple years of data, a multi-year weight is needed. Multi-year weights are only available for data years 2002-2008, and for select two-, three- and five-year combinations from 2009-2020. Survey data from 2009 and after cannot be combined with earlier years. Please complete the EPI data request form to request more information on multi-year survey weights.


• Before analyzing the data below, read our analytic considerations.


• For any published analysis using downloadable CHS data, please reference the URL of this webpage, the CHS year(s) analyzed and the date on which the dataset was downloaded (suggested citation below). On occasion, updates are made to some variables.
