What you should know about this indicator

  • Not all students enroll in school at the same age. This indicator shows how many students are attending a certain level of education, regardless of whether they are considered to be within the expected age range for that level.
  • It captures the total number of students enrolled at a specific education level, expressed as a percentage of the population in the official age group for that level.
  • For example, if upper secondary school is designed for ages 15 to 17, the gross enrolment ratio compares total enrolment at that level to the population of 15- to 17-year-olds.
  • A high value means many people are accessing education at that level, but it doesn’t necessarily mean that they are in the appropriate grade for their age.
  • The gross enrolment ratio includes students who are younger or older than expected due to late entry, early entry, or grade repetition.
  • The data comes from administrative records, such as school enrolment reports, and from population estimates, usually provided by UN or national sources.
  • A gross enrolment ratio close to or above 100% can indicate strong system capacity, but it doesn’t tell us whether every school-age child is enrolled.
  • This indicator is best understood when used together with the net enrolment rate, which focuses on age-appropriate participation.
  • One limitation is that the gross enrolment ratio can exceed 100%, which may require further data to understand the reasons — such as whether students are repeating grades or starting school late.

Total enrollment in secondary education, regardless of age, expressed as a percentage of the population of official secondary education age. GER can exceed 100% due to the inclusion of over-aged and under-aged students because of early or late school entrance and grade repetition.

How we process data at Our World in Data

All data and visualizations on Our World in Data rely on data sourced from one or several original data providers. Preparing this original data involves several processing steps. Depending on the data, this can include standardizing country names and world region definitions, converting units, calculating derived indicators such as per capita measures, as well as adding or adapting metadata such as the name or the description given to an indicator.
