We have tried to minimize the danger of breaches of respondent anonymity by aggregating critical variables such as geographic location and occupation/industry up to less specific levels than those provided by the respondent. Public-use data are available for download from the Data Center. The risk of disclosure of confidential information of research participants is minimal for these datasets.

In some cases, the removal of potentially identifying information would significantly impair the analytic potential of the data. Access to these data is only granted following an application process designed to ensure that this sensitive information is released only to people who meet stringent conditions.
