This grant provides funds for the creation and operation of the Administrative Data Research Institute (ADRI), a national membership organization designed to provide services and set standards for the global network of Administrative Data Research Facilities (ADRFs). An ADRF is a data intermediary, i.e., an institution that facilitates researcher access to private or sensitive data owned or held by corporations and government entities. To become a member of the new ADRI, member ADRF’s would have to provably maintain high data standards and practices, particularly regarding data privacy and security. In return, the ADRI would provide member institutions with expert advice and leadership concerning the many technical, legal, political, or privacy challenges that data intermediaries face. Above all, the ADRI would help engender trust in at least three domains where it is much needed: among the member intermediaries when it comes to arrangements for linking their data; among the data producers when it comes to negotiating data use agreements with member intermediaries; and among the public and their policymakers when it comes to allowing administrative data containing sensitive information to be reused through member intermediaries for research purposes. Grant funds support initial start-up and operational costs of the new network for a period of two years.
