Record Linkage, Privacy and Statistical Policy
Lawrence H. Cox and Robert F. Boruch
Abstract:Record linkage technology is a valuable statistical tool. It can be used to enhance the quality, completeness and usefulness of data. Record linkage also can be used to check the accuracy of data, demanding fewer resources and imposing less respondent burden than other verification methods. In developing formal record linkage policy or informal policy guidelines, organizations must cope with several competing issues regarding the need for privacy and the benefits and costs of record linkage. This paper discusses recent approaches to using the technology and addressing the problems it generates. Our observations are presented from the perspectives of both data user and data supplier.
Keywords:Record linkage; statistical matching; exact matching.
