Secondary school enrolment (gross)

Gross enrollment ratio is the ratio of total enrollment, regardless of age, to the population of the age group that officially corresponds to the level of education shown. Secondary education completes the provision of basic education that began at the primary level, and aims at laying the foundations for lifelong learning and human development, by offering more subject- or skill-oriented instruction using more specialized teachers.

How to read this chart

Unclassified means the provider did not supply an explicit observation/estimate flag. It does not mean the value is unreliable. Source or methodology changes can affect trends across editions.

Countries publish data on different schedules. A shorter line or a gap means the source has no value for that country and year. Missing values are not zero. Only separately sourced official estimates or projections may fill gaps; we do not invent intermediate values. Use Table to inspect individual years.

The source-check date tells you when we retrieved the data, not the year it describes. Use the observation year when citing a value.

Gross education ratios can exceed 100% because the numerator can include students outside the official age group used in the denominator.

Compare the same definition and period. Differences are descriptive, not causal. National measurement methods may differ; crude rates are not age-standardised. Missing uncertainty intervals in this feed do not mean an estimate is exact.

Interpreting this indicator

Gross secondary enrolment compares all enrolled students with the population of the official age group. Over-age and under-age students can lift the ratio above 100%. Differences in education systems and reference school years matter for comparisons.
