What drives trust in government? This report presents the main findings of the first OECD cross-national survey on trust in government and public institutions, representing over 50 000 responses across 22 OECD countries. The survey measures government performance across five drivers of trust – reliability, responsiveness, integrity, openness, and fairness – and provides insights for future policy reforms. This investigation marks an important initiative by OECD countries to measure and better understand what drives people’s trust in public institutions – a crucial part of reinforcing democracy.
