What you should know about this indicator

  • Many children who are old enough for primary school are not attending any kind of school — this indicator shows how many are missing out on education.
  • It captures the share of children in the official primary school age range who are not enrolled in primary or secondary education.
  • The indicator is calculated by subtracting the number of enrolled primary-age children (regardless of the level of education) from the total number of children in that age group, and expressing the result as a percentage.
  • These children may have never enrolled, may have dropped out, or may be starting late and not yet entered school.
  • A high out-of-school rate highlights the need for improved access and targeted policies to reach excluded groups. When disaggregated, the indicator helps identify gaps by sex, location, or socioeconomic status.
  • The data comes from administrative records and household surveys that collect information on enrolment by single year of age and compare it with population estimates for the same group.
  • As with all estimates, there are limitations. Differences in data sources, enrolment definitions, and the timing of data collection (especially if late in the school year) can affect accuracy.

The number of students of the official age for primary education is subtracted from the total population of the same age. The result is expressed as a percentage of the population of the official age for primary education.
