Latin America will have 38.3 million fewer school-age people between 2020 and 2050, a demographic shift that will reshape teacher demand, infrastructure needs, and the distribution of education resources across the region, according to a joint analysis by the Economic Commission for Latin America and the Caribbean (ECLAC) and the United Nations Educational, Scientific and Cultural Organization (UNESCO). The findings appear in issue 122 of Population Notes, ECLAC’s journal. The study warns that this transition is already reaching classrooms and will move gradually through every education level. It calls on governments to anticipate the change, plan from a territorial perspective, and sustain investment in education. The central thesis is that declining enrolment must be treated as an opportunity to close gaps, not as a justification for budget cuts.
The region has been undergoing a rapid demographic transition for decades, with the fertility rate falling from 5.8 children per woman in 1950 to 1.8 today. Between 2018 and 2023, the sharpest declines in births were recorded in Argentina, Costa Rica, Chile, and Uruguay. In Chile, births fell by 20.3% over that period, and the total fertility rate dropped to 1.17 children per woman. Annual births in Chile are projected to decrease from around 176,000 in 2023 to 144,000 in 2050. Migration has also contributed to births and population growth in receiving countries such as Chile.
The study estimates that demographic change could free up around 30% of the financial resources currently used at each level of education by 2050, assuming expenditure per student remains constant. However, major gaps persist: only 72% of children of pre-primary school age are enrolled, and around 41% do not complete secondary education. Simulations for Argentina, Costa Rica, and Uruguay show that, if coverage levels remain unchanged, these countries would have around 20% fewer students by 2030. By 2050, their education systems could shrink by between 32% and 40%. The authors argue that freed-up resources could be redirected to reduce class sizes, expand coverage, and strengthen early childhood, secondary, and technical and vocational education.
The effects will differ across education levels, with reduced demand potentially easing coverage expansion in early childhood education while secondary education still requires efforts to retain and graduate adolescents.
Simone Cecchini, Director of the Latin American and Caribbean Demographic Centre (CELADE)–Population Division of ECLAC, stated: “We are facing a structural change that will progress at different speeds, but will ultimately affect every country. Anticipating its consequences will make it possible to take better public policy decisions.”
The report also stresses that declining birth rates will not affect every community equally. Some schools will lose students, while others may maintain or increase enrolment due to migration or local population growth. Planning must therefore integrate data on births, enrolment, migration, and geographical location.
Alejandro Vera, Education Specialist at the UNESCO Regional Office in Santiago, noted that planning based on territorial data can help avoid delayed decisions and improve the relevance of education. The study recommends anticipating where education provision must be reorganized, resources redistributed, or specific services strengthened. Smaller cohorts do not automatically imply lower education needs, as the region must still bring out-of-school children into the system. To convert this demographic shift into an opportunity, countries will need to safeguard investment in education and direct resources toward the people and territories that need them most. Declining birth rates alone, the authors conclude, will not deliver better education systems.
