The digitalisation of public services is a priority both in the European Union’s Digital Decade strategy and in the National Plan of Recovery and Resilience (NPRR). However, older informal caregivers often encounter significant barriers in accessing these services, mostly due to their insufficient digital skills. In this context, analysing the relationship between older informal caregivers and access to/use of digital public services (e-government) is crucial, especially in an era characterised by rapid technological changes. The limited availability of high-quality survey data represents a significant barrier to identifying the challenges faced by this population and to introducing targeted policy measures and interventions. This study aims to map the existing datasets that collect information on the use of digital public services by older informal caregivers with the goal of assessing both their potentials for research and limits.
