Upper Secondary Attainment

Adults 25+ who completed upper secondary or higher (%)·Higher is better — rank 1 leads·Published by UNESCO Institute for Statistics (UIS)

We hold 23 editions of this indicator, from 2000 to 2023 — 2,078 rows in total, and 95 countries in the newest.

23 editions (2000–2023), 54 to 116 countries. The share of adults aged 25 and over who finished upper secondary education or went further — a stock measure of what a country’s working-age population actually holds, rather than what its schools are currently doing. Female and male rates are stored beside the headline. It is the natural companion to `mean-years-schooling`: that one counts years, this one counts whether a threshold was crossed. ⚠ Editions reporting fewer than 50 countries are not written — that drops UIS’s trailing stub year, which opens with a handful of early reporters, and any thin historical year. ⚠ UIS ranks nobody, so no rank is stored; the POSITION on the statistics page is derived here by ordering the score and labelled as ours.
