Indicators Part I: Population and School Enrollment

The indicators in this section provide data on the population and school enrollment of the G-20 countries.

• Indicator 1 examines the school-age population as a percentage of the overall population. It focuses on the age group most likely to be enrolled in education, as well as on two subsets of that age group: those most likely to be enrolled in primary or secondary education and those generally of higher education age.
• Indicators 2 and 3 describe the percentage of the population that is enrolled in formal education in the G-20 countries and changes in enrollment over a 10-year period. They focus on the four age groups that generally correspond to the ages of those enrolled in preprimary education, primary and lower secondary education, upper secondary education, and higher education.
• Indicator 4 describes the prevalence of international and foreign students studying in higher education in the G-20 countries, including students in academic programs below the doctoral level and at the doctoral level. It provides an indication of the internationalization of higher education and student mobility.

The indicators in this section draw primarily on data from Education at a Glance 2013: OECD Indicators (OECD 2013a).
