What you should know about this indicator

  • This indicator shows the share of children who are the right age for primary school but are not enrolled in primary or secondary education.
  • It focuses on those in the official primary age range — typically 6 to 11 years old — who are not attending any formal level of education.
  • Some may have never entered school, others may have dropped out, or they may not yet have started due to delayed entry.
  • Children who are the right age for primary but are already in secondary school are considered enrolled and are not counted as out of school.
  • The indicator is calculated by subtracting the number of primary-age children enrolled in primary or secondary education from the total in that age group.
  • Data sources include enrolment records from school systems and household surveys that help identify children not captured in administrative data.
  • Estimates may be affected by inconsistencies between sources, late school entry, or surveys conducted at different times of year.
  • Children who are enrolled but not attending regularly may not always be captured correctly, depending on how data is collected and defined.
