Adult & continuing education sits within Education, the sector building human capital — the slowest-moving but ultimately largest driver of long-run economic growth — a category with a real, cited scale: government expenditure on education is 3.57% of world GDP, 2023 (World Bank). Adult & continuing education is one of 16 of the category's 20 items directly backed by UNESCO's ISCED 2011 framework, UN SDG indicators, or OECD's PISA program, depending on the specific segment, rather than an editorial judgment call.
