Child Mortality (under 5) by Country — Every Decade Since 1800

Every statistic here represents the quietest of tragedies: a life unlived before its fifth year. Behind the raw digits lies the profound fragility of infancy, a reality that dictates the contours of family life across the globe. As of the 2020s, the spectrum of risk is wide, ranging from 1.9 per 1,000 births in Finland to 113.8 per 1,000 births in Nigeria across 157 countries. We examine these rates to honor the individual experiences tucked within the data, tracking every country MYRIAD covers, decade by decade, to reveal the shifting tides of human survival.

The historical arc of these numbers reveals a transformation in the human story. Once, the loss of a child was a common expectation; today, it is a rare catastrophe in much of the world. While top-ranking nations like Finland, Norway, and Singapore have reached rates as low as 1.9 to 2.2 per 1,000 births, others remain in a state of crisis. The gap between the median—16 per 1,000 births in Costa Rica—and those at the bottom, such as Nigeria at 113.8, illustrates the vast, persistent inequalities that still define our global geography.

Where you are born creates a set of probabilities that stay with you for a lifetime. If a child is born in a region where the rate is 75 per 1,000 births, as is the case in Sierra Leone, Somalia, or South Sudan, their early years are navigated against a very different reality than a child born in Spain or South Korea. These numbers dictate the reach of medicine, nutrition, and infrastructure. By tracking these figures through time, we can observe the impact of progress.
