Mean years of schooling completed by the population aged 25 and above, in years, by country and year, from the UNESCO Institute for Statistics (https://api.uis.unesco.org/api/public/data/indicators). Each row is one (year, area): MYS.1T8.AG25T99. Method: keyless UIS Data API v1; one request for the single indicator; null values dropped. Units: years. Caveats: mean years of schooling is estimated from censuses and household surveys and is sparsely observed for many countries; this slice carries no regional aggregates and no estimate flags; the latest 1-2 years are provisional and revised. Coverage: worldwide, 1970 to 2024, yearly granularity. Provenance: UNESCO Institute for Statistics, CC BY-SA 4.0 — please cite the UIS with the extraction date. Primary key: (indicator_id, area, year). Join keys: iso3 (ISO 3166-1 alpha-3), year. Cadence: refreshed yearly. Sample use: filter iso3='KOR' to track Korea's schooling expansion.
