OECD:


The latest Survey of Adult Skills highlights a mixed global picture of literacy, numeracy and adaptive problem solving proficiency. Finland, Japan, the Netherlands, Norway and Sweden excel in all these areas, with significant proportions of their adult populations demonstrating advanced abilities. However, on average across OECD countries, 18% of adults do not even have the most basic levels of proficiency in any of the domains.

Thirty-one countries and economies participated in the 2023 Survey of Adult Skills. The survey, a product of the OECD Programme for the International Assessment of Adult Competencies (PIAAC), provides a comprehensive overview of adults’ literacy, numeracy, and adaptive problem solving skills – skills that are fundamental for personal, economic, and societal development.
