Users are expected to provide us with information on published materials that they have authored which reference Panel Study of Income Dynamics data files. These materials will be included in an on-line public database containing bibliographic records.

Information from the user registration page may be used in summary form to provide usage data to sponsoring agencies. Unique identifiers (such as e-mail address) are collected from public data users to verify the user's identity, and for use as identifiers in our record system. Although the data user list will not be shared with third parties, the Panel Study of Income Dynamics may use the list for electronic mail user surveys, announcements of new data products, data alerts, and other purposes.

When registering for access to PSID data files, users may opt to receive data product and data alert announcements via electronic mail.
