The CPES Web site provides information about the thousands of variables that users may access in the public-use files for CPES and its constituent surveys: the National Comorbidity Survey Replication (NCS-R), the National Survey of American Life (NSAL), and the National Latino and Asian American Study (NLAAS). Data and documentation files for all of these surveys are available at:
In addition, there are a small number of variables that are available only as restricted-use files. Please note that we have not harmonized these data but have provided tables for each file that list the names of all variables along with their labels and formats.
These data also have not been cleaned to the same standards as those data in the public release files.
Analysts wanting to request the restricted files should apply online for access to the data. Authentication is required to apply for access. Analysts wishing geographic identifiers should contact firstname.lastname@example.org. Distributions for restricted data can be viewed in the Interactive Codebook section of the CPES Web site.
