Europe’s ageing population, declining mortality rates, changing family situations, and increased mobility and migration, all mean rapid social change. They also mean greater challenges for EU welfare systems.
Traditional tools for the analytical study of such societal challenges have shown serious limitations. To better understand these challenges, new tools will be created to exploit the big data nowavailable. Long-term investments in the development and construction of longitudinal population registers and large research databases will also help to open up avenues for new linkages between different data sources (i.e. administrative and health data).
