The dataset I wish to analyze is restricted. What do I have to do to get the data?

Information on how to obtain restricted data can be found on the study home page. When you click the "Access Restricted Data" button, you will find instructions for accessing and preparing the restricted data application.

Before you begin filling out the paperwork, you should know the following:

  • Restricted data are generally only made available to PhD-level researchers and their staff; these data are typically not appropriate for undergraduate-level projects or class projects
  • The review process typically takes 2-4 weeks, but it may take more or less time depending on the number of revisions needed
  • You'll need to fill out paperwork describing your project and how you'll protect the data. This may include providing technical specifications on the security of your work environment
  • You will need the Institutional Review Board at your institution to review your project and agree that it can go forward as described

ICPSR does not discourage the use of restricted data. In fact, we've put a lot of effort into building systems that make these data available to researchers. We are, however, very serious about protecting respondent confidentiality and ensuring that sensitive data are used appropriately.
