The Gateway to Global Aging Data Enclave is a secure remote-access computing desktop hosted on the National Institute on Aging's LINKAGE platform. Through the Enclave, users are provided access to the Gateway's Harmonized data products and original survey data. The Enclave also provides users with analytic packages like R, SAS, and Stata and productivity software like Adobe Acrobat Reader, Microsoft Excel, Microsoft Word, and Notepad++.

Enclave Access

To apply for Enclave access, researchers must first create a Gateway user account and then fill out an Application for a Gateway Enclave Workspace.

Data may not be exported from the Enclave. Users may only export statistical summaries (i.e. frequency tabulations, means, variances, regression coefficients, etc.) and analysis programs. All output will be monitored and approved by a Gateway compliance officer prior to download.
