ICPSR Statement on Safeguarding Confidentiality

ICPSR considers the protection of confidentiality in archived data to be of paramount importance in its service to the social science research community. Since its inception in 1962, ICPSR has routinely subjected all data deposited in the archive to rigorous examination with respect to disclosure risk. All data collections acquired by ICPSR undergo stringent confidentiality reviews to determine whether the data contain any information that could be used -- on its own or in combination with other publicly available information -- to identify respondents. Should such information be discovered, the sensitive data are altered after consultation with the principal investigator to create public use files that limit the risk of disclosure.

Note: This statement applies to all data collections in the ICPSR Archive, with the exception of data designated as restricted and data in the Publication-Related Archive.
