Can I share restricted data using NACDA?

Restricted data (whether using NACDA or ICPSR), requires creating a restricted-use data deposit and dissemination agreement (RUDDA) and a restricted data user agreement (RDUA), therefore, you would need to factor in time for this process in your data management plan; these agreements are typically created in collaboration with university legal teams. For any data collection, in order to ensure discoverability, accessibility and reusability, we strongly encourage data providers to create a public-use version of the materials – please keep this in mind as you and your team prepare for your data collection. If you are interested in proceeding with restricted-use data we recommend you refer to ICPSR’s Data Management Plans and Grant Support page so you can get an estimate from ICPSR. Depending on the level of restriction required, the costs vary, for instance there are often costs associated with setting up a virtual data enclave (VDE) for the data.
