Research Data Centers (RDCs) have been the poor relations of data access. Recently, however, developments in technology have altered the landscape. Whilst effective anonymization becomes more difficult, RDCs are now able to surmount many of their drawbacks and make more use of their advantages. Hence, there has been a resurgence in RDCs and analysis of the most confidential microdata. However, this has raised new issues in terms of disclosure control of outputs, transparency of access, international data sharing and so on. This paper reviews developments and provides an overview of providing access to confidential microdata, concentrating on developments in RDCs and "data enclaves." It looks at the data access "spectrum," reviews what we know about managing RDCs, highlights known problems and unresolved issues, and discusses some of the practical barriers to improved data access.
