Physical Data Enclave

Access to some DSDR studies is through the ICPSR physical data enclave. Researchers must come to the Perry Building on the University of Michigan campus in Ann Arbor, MI to access the data. Data in the physical data enclave typically contain highly sensitive personal information, data from protected populations, or data in which respondents can be identified. An Application for Use of the ICPSR Data Enclave is required for access. Other study-specific requirements may apply. The application components are described in more detail on the study page for applicable studies.

When using the physical data enclave, several guidelines are in effect:

• Access to the enclave is by appointment only
• Investigators cannot bring laptops or other electronic equipment into the enclave
• The enclave is equipped with a Windows computer with the Microsoft Office Suite and the SPSS, SAS, and Stata statistical packages. Arrangements must be made in advance for other software
• The computer is not connected to the Internet, and the removable media ports are disabled
• A DSDR or ICPSR staff member is present at all times when a researcher is using the enclave. The staff member inspects and approves all material brought into the enclave
• All output, notes, and other material must be submitted for disclosure review before the investigator leaves the enclave. Handwritten notes are discouraged.
• DSDR staff will conduct a disclosure review of all files that the investigator wants to use after leaving the enclave
• Approved analysis output will be sent to the researcher electronically
