This virtual high-level roundtable will bring together representatives, experts and stakeholders from across OECD countries who have taken action to put child well-being at the top of the policy agenda. They will discuss their ongoing progress, the types of actions they think are most relevant to ensure that the needs of children are well understood and properly assessed, as well as how we can improve our child well-being policy monitoring and steering efforts. This will also be the opportunity for the OECD to present its new report Measuring What Matters for Child Well-being and Policies, which lays the groundwork for improved child well-being measurement and better data to inform better child well-being policies. The new report provides timely insights into priorities for child data collection and measurement as countries begin to recover from the COVID-19 pandemic. Priorities highlighted include overcoming the poor data coverage of children in the most marginalised situations as well as properly capturing protective factors in children’s families and neighbourhoods that promote resilience in children at times when the odds are stacked against them.
