Innovative Solutions in Providing Access to Micro-data

State of the art: An overview of policy and practice on release of microdata Statistical offices must provide data products that are both useful and have low risk of confidentiality disclosure. Recognizing that deidentification of data is generally inadequate to protect their confidentiality against attack by a data snooper, agencies can release microdata under policies of restricted access or can release products of restricted data. Under a policy and practice of restricted access, administrative procedures impose conditions on user access to data. These conditions may depend on the type of data user; conditions may be different for interagency data sharing than for external data users. Various restricted access policies (Jabine 1993a,b) have been implemented in the last twenty years.
