Restricted Data

ICPSR ensures respondent confidentiality within public-use versions of the datasets. The vast majority of ICPSR data holdings are public-use files with no access restrictions. Sometimes the protective measures taken to reduce disclosure risk would significantly degrade the research potential of the data. In these cases, ICPSR provides access to restricted use versions that retain confidential data by imposing stringent requirements for accessing them. (more)
