Fifty years ago, the average Latin American woman had four to five children. Today, a clear majority of the region’s countries have fallen below the 2.1 replacement rate — and the decline is accelerating. According to UN projections for 2026, Latin America and the Caribbean will account for just 9.3 million of the world’s roughly 132 million births, a 7% share that reflects a region rapidly ageing out of its once-defining demographic youth.
A Two-Continent World
The global birth map is increasingly dominated by two continents. Asia is expected to see 64.9 million births in 2026 (49% of the total), driven by India, Indonesia, and Pakistan. Africa will add 47.6 million (35.9%), with sub-Saharan nations like Nigeria recording birth rates above 40 per 1,000 people.
Latin America’s 7% still outpaces Europe (6.1 million, 4.6%) and North America (4 million, 3%), but the trajectory is clear: the region is converging with the ageing economies of the developed world.
Why the Drop Is So Fast
ECLAC’s Demographic Observatory 2025 found that 76% of Latin American countries now have fertility rates below replacement. The regional average stands at 1.8 children per woman, and several nations — Chile, Uruguay, Costa Rica, Cuba, and Jamaica — have dropped below 1.3, entering what demographers call “ultra-low fertility.”
The speed has surprised specialists. Argentina, Chile, and Uruguay have seen births nearly halve in a single decade. Uruguay became the first country in the region to record more deaths than births in 2021.
A June 2025 UNFPA report added nuance to the narrative that falling births simply reflect women choosing independence. Surveying 14 countries, the agency found that one in five people do not expect to have the number of children they want, citing economic insecurity and housing costs as leading barriers.
Colombia’s Free Fall
DANE, the national statistics agency, recorded 445,011 births in 2024 — the lowest in over 25 years and a 32.7% drop since 2015. The country lost 70,538 births in a single year compared to 2023, a 13.7% decline accelerating a slide underway since 2018.
The steepest collapse has been among teenagers aged 15 to 19, where births fell 51.1% in ten years. Meanwhile, women are having children later: the average age of motherhood in Bogotá now stands at 28.3 years.
The Dividend Window Is Closing
Latin America’s demographic dividend — the economic boost from a large working-age population relative to dependents — is running out. ECLAC data shows the region’s dependent population began growing faster than its workforce after 2020.
For Colombia, the stakes are concrete: fewer workers paying into underfunded pensions, a shrinking consumer base, and mounting healthcare costs. Banco de la República researchers have warned the country’s population could begin outright decline within the next decade, well ahead of previous projections. Latin America is not yet Europe or East Asia, but the gap is narrowing faster than anyone expected.
