Korea, Rep.: Educational attainment, at least completed lower secondary, population 25+, total (%) (cumulative)

Key figures

What the numbers say

In 2024, Korea, Rep.'s educational attainment, at least completed lower secondary, population 25+, total (%) (cumulative) rose 0.39 percentage points on 2023 (from 89.56% to 89.95%).

Across the 20 yearly changes before that (2004 to 2023), the average change was +0.49 percentage points and a typical year strayed about 1.71 percentage points from that (the standard deviation). This year's change was 0.1 standard deviations below that average, so it was an ordinary year: it sits within the range of normal year-to-year movement.

On record, the biggest yearly rise was 5.04 percentage points in 2010 and the biggest yearly fall was 5.1 percentage points in 2009. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.

From 2015 to 2024 the straight-line trend is upward, about 0.4 percentage points a year. A straight line explains 95% of the movement over 10 observed years.

Worked out from the yearly values above. How the checks work: standard deviation, z-scores and straight-line trends.

A straight-line projection, tested first

Extending that straight line gives about 91.07% for 2027. We show this only because the same method, fitted on earlier years, predicted 2022 to 2024 better than "no change" would have: its average miss was 0.18%, against 0.92% for assuming no change. Treat it as a continuation of the recent pattern, not a forecast of events: it cannot see a recession, a policy change or a revision to the data.

What this measures

The percentage of population ages 25 and over that attained or completed lower secondary education.

Limitations: Caution is required when using this indicator for cross-country comparison, since the countries do not always classify degrees and qualifications at the same International Standard Classification of Education (ISCED) levels, even if they are received at roughly the same age or after a similar number of years of schooling. Also, certain educational programmes and study courses cannot be easily classified according to ISCED. This indicator only measures educational attainment in terms of level of education attained, i.e. years of schooling, and do not necessarily reveal the quality of the education (learning achievement and other impacts).
