This workshop, convened collaboratively by the German Data Forum and the UK Data forum, was designed to explore recent developments in both countries with respect to improved research access to administrative data. Presentations would give participants an overview of the techniques being developed in Germany and the UK to provide secure access to person-level data. The workshop would also provide an opportunity for discussion about the changing legal environment for research access to personal data and the ethical issues surrounding such uses. The main topic for discussion would be data infrastructure issues and common concerns relating to access, both within Europe and more widely, in terms of access to and linkage between personal data for research into social, economic, environmental and health matters. The ultimate aim is to ensure ways of accessing and analysing data to shed light on policy effectiveness and efficiency at both national and supranational levels.
