Secondary School Enrolment

50 years, 1971–2024 · 109 countries

The gross secondary enrolment ratio divides everyone in secondary school, at any age, by the population of official secondary-school age. UNESCO has tracked it since 1971, and it is still the broadest available read on whether a country’s teenagers are in school at all.

This site holds every year from 1971 to 2024, read from UIS’s own data and stored exactly as published.

Precision

The headline is stored to 13 decimals, as published.

Rounded by this site

Never. Tables on screen may show fewer decimals; the files never do.

Changed by this site

Reshaped into one row per country: regional and income-group totals are left out, only the columns listed are kept, each row gets its ISO 3166 code, and some country names are brought to one spelling. No value is recalculated, rescaled or rounded.

Produced by the UNESCO Institute for Statistics and pulled through the World Bank’s indicator API (SE.SEC.ENRR).
