In the 2020s, child mortality (under 5) in Costa Rica stands at 16 per 1,000 births — ranking #79 of 157 countries. In 1900 it was 350 per 1,000 births. (Source: UN IGME / World Bank / Gapminder, compiled by MYRIAD)
To look at child mortality is to gaze upon the fragile boundary between infancy and growing up. These statistics are not merely figures but the quiet weight of human lives lived and lost, shaping the very architecture of families and communities. For centuries, the measure of how many children out of every 1,000 born failed to reach their fifth birthday defined the emotional landscape of Costa Rican households, marking the difference between a childhood realized and a void left behind.
The historical arc reveals a profound transformation. In the 1800s estimate, child mortality stood at 420 per 1,000 births, ticking down slowly to reach 350 per 1,000 births in the 1900s estimate. The decline then accelerated steadily: dropping to 180 in the 1950s, 80 in the 1980s, and 32 in the 2000s. This trajectory suggests a world fundamentally rewritten, moving toward a 2100s projection of 2.68.
Today, a child born in Costa Rica navigates a landscape where mortality stands at 16 per 1,000 births, ranking #79 of 157 countries. This is a stark departure from an infant entering the world in the 1840s estimate, who faced a grim 392 per 1,000 births mortality rate. Survival has shifted from a precarious gamble to a reliable expectation, altering the trajectory of human existence within this nation.
