Identity Protection

In preparing data for public release, a number of procedures were performed to ensure that the identity of CPES research subjects could not be disclosed. For example, direct identifiers have been omitted from datasets, some variables deleted, and some characteristics recoded or masked if they could be combined with others to identify individuals.

The disclosure protection allows nearly all of the data to be publicly released, takes into consideration the most likely analytic uses of the data, and helps ensure the confidentiality of records.
