In recent decades, UNICEF has established surveys and extensive crossnational databases of indicators relating to the well-being of children across the globe (e.g. UNICEF-supported Multiple Indicator Cluster Survey (MICS) programme). Once compiled by the custodian, SDG indicators are submitted to the global SDG database (managed by the UN Statistics Division) along with interpretation of the data and trends for the annual SDG progress reports. And UNICEF, as an SDG custodian, continues to commit to improving global data for children by supporting national and international partners to meet the data demands of the SDGs. The unique contribution of this paper is that it opens discussion around the SDGs and social progress which is both child-focused and high-income country-focused. The following section introduces the main findings of the paper, including a summary table of the data available for monitoring the position, and the recent development of high-income countries in the SDG challenge. Section 3 addresses conceptual and methodological issues related to developing a framework of indicators for child-focused SDGs in high-income countries.
