Restricted-use data are distributed in cases when removing potentially identifying information would significantly impair the analytic potential of the data, or in cases where data contain highly sensitive personal information and cannot be shared as a public-use file. In these circumstances, ICPSR provides access to a restricted-use version that retains the confidential data but requires controlled conditions for accessing them. Access is only granted following an application process during which researchers agree to follow strict legal and electronic requirements for maintaining data confidentiality. The sections below provide further information on locating, applying for, and accessing restricted data at ICPSR.
