This grant funds a dozen conferences to be held over two years that are designed as community-building exercises for a new Administrative Data Research Network (ADRN). The ADRN is a linked network of Administrative Data Research Facilities, research centers devoted to facilitating the use of administrative data by researchers by lowering transaction costs and increasing the reproducibility of research conducted on administrative data. Conference topics will focus on common difficulties encountered when working with administrative datasets, including securing data access, privacy and anonymity, data ethics, documenting and versioning data, data use agreements, and archiving. Conference outreach will target not only researchers, but key officials in government and industry who have access to administrative data. If successful, these conferences will serve as important gatherings to build consensus around standards, priorities, and best practices in the growing community of researchers working with administrative data.
