How Does DSDR Protect Respondent Confidentiality?

DSDR works with data providers to ensure respondent confidentiality by removing, masking, or collapsing variables within public-use versions of the datasets. Sometimes these protective measures that are taken to reduce disclosure risk would significantly degrade the research potential of the data. In these cases, DSDR provides access to restricted-use versions that retain confidential data by imposing stringent requirements for accessing these data.
