Despite having advanced social protection systems, OECD countries still face challenges in identifying, enrolling, and providing benefits and services to all those in need. Even when programmes are well-designed and adequately funded, cumbersome enrolment processes and challenges in service and benefit delivery can be an obstacle to the full take-up of social programmes. Advances in digital technologies and data can go a long way towards making social protection more accessible and effective. This report presents a stocktaking of OECD governments’ strategies to identify individuals and groups in need, collect and link (potential) beneficiary data across administrative and survey sources, and apply data analytics and new technologies to improve programme enrolment and the benefit/service delivery experience – all with the objective of reaching people in need of support in OECD countries.
