One-year PUFs consist of individual records obtained from each survey year (CHIS 2001 – 2023). One-year PUFs contain data at the state-level and include variables that minimize the risk of indirect identification of CHIS respondents. Variables that are not included in the one-year PUFs are available in our confidential dataset, which can be accessed via a Data Access Center (DAC) project. Alternatively, certain variables not included in the one-year PUFs may also be available in the two-year PUFs.  

One-year PUFs are available by direct download for CHIS 2001 to 2023 years. The files are available for Adult, Teen, and Child age groups and can be downloaded in SAS and Stata data formats.  

Please see the data dictionaries below to review the variables available in each one-year PUF. The data dictionaries also include information on survey methods and how to use the CHIS sample weights. View the detailed methodology reports for more information. Each link below contains only the data dictionary, not the data file itself.
