A coherent and effective set of indicators is essential to understanding the impact of any policy action. Comprehensive and regularly updated data sets the foundation for this critical step in the policy life-cycle. In Ireland, a shared monitoring system across three regional assemblies (RDM Hub) allows the visualisation of a range of relevant socio-economic and environmental indicators to understand the performance of each region in terms of achieving the objectives outlined in their respective Regional Spatial and Economic Strategies (RSES). This session will showcase the RDM Hub which provides an example of the transformative impact of open data and digitalisation, making critical information accessible for policy-makers and the public.
