‘Historic milestone’ as global child mortality hits record low of 4.9 million in 2022

Story: 2024 C.E.  |  Last updated: April 28, 2026

The number of children dying before their fifth birthday has dropped to its lowest point in recorded history. New UN estimates released in 2024 C.E. confirmed that global child mortality fell to 4.9 million deaths in 2022 C.E. — a figure that would have been unimaginable just a few generations ago, and a measure of how much collective human effort can accomplish when directed at a shared goal.

At a glance

• Child mortality rate: The total number of under-five deaths worldwide fell to 4.9 million in 2022 C.E., the lowest figure ever recorded in the modern era of global health tracking.
• UNICEF data: The estimates were produced jointly by UNICEF, the World Health Organization, and the United Nations Population Division, drawing on the most comprehensive data available from national health systems.
• Long-term progress: Global under-five deaths have fallen by more than 50% since the year 2000 C.E., when roughly 9.9 million children died before their fifth birthday each year.

Why this number matters

Behind every statistic is a child who lived — a life that would not have been saved in an earlier decade. Five million is still a devastating number. But the direction of the trend, sustained across more than two decades and across vastly different countries and contexts, is one of the most important humanitarian achievements of our time.

The drop reflects decades of investment in vaccines, oral rehydration therapy, malaria bed nets, skilled birth attendants, and community health workers. None of these interventions is glamorous. All of them work.

Pneumonia, diarrhea, malaria, and complications from premature birth remain the leading killers of young children globally. Each of these causes is largely preventable or treatable with existing tools — which means the gap between current mortality and zero preventable child deaths is, in large part, a gap of resources, access, and political will rather than scientific knowledge.

Where progress has been deepest

Sub-Saharan Africa and South Asia have seen some of the steepest declines in child mortality over the past two decades, driven by the expansion of community health worker programs, wider vaccine coverage, and improvements in access to clean water and nutrition. Countries including Ethiopia, Rwanda, and Bangladesh have posted reductions in under-five mortality that rank among the fastest in global health history.

Rwanda’s trajectory is particularly striking. In the aftermath of the 1994 C.E. genocide, the country had one of the highest child mortality rates on the continent. By the 2020s C.E., it had cut that rate by more than 80%, largely through community-based health insurance, local health cooperatives, and a strong national commitment to primary care.

Indigenous and rural communities, historically left out of national health gains, have begun to see greater inclusion through targeted outreach programs — though significant disparities within countries remain one of the most persistent challenges in global child health.

How vaccines changed the math

The expansion of childhood immunization is one of the clearest drivers of this progress. The World Health Organization estimates that vaccines prevent between four and five million deaths per year across all age groups, with young children accounting for the largest share. The introduction and scaling of vaccines against rotavirus, pneumococcus, and Haemophilus influenzae type b — all major causes of child death — has been central to the post-2000 C.E. decline.

Gavi, the Vaccine Alliance, which supports immunization in lower-income countries, estimates it has helped vaccinate more than one billion children since its founding in 2000 C.E. and averted more than 17 million future deaths. That scale of impact, achieved through a partnership between governments, the private sector, and civil society, represents a model for global health that has influenced how the world thinks about coordinated action on other threats.

What remains unfinished

The 4.9 million figure is a record low — and it is still far too high. The UN agencies behind the data are clear that progress has been uneven. Children born in conflict zones, in the poorest rural households, or to mothers without access to prenatal care remain far more likely to die before their fifth birthday than their peers in wealthier settings.

UNICEF’s data portal shows that a child born in sub-Saharan Africa is still roughly 15 times more likely to die before age five than a child born in a high-income country. That gap has narrowed, but it has not closed. The same tools that produced this record low — vaccines, trained health workers, clean water — are still not reaching every child who needs them.

Neonatal deaths, those occurring in the first 28 days of life, now make up nearly half of all under-five deaths and have proven harder to reduce than deaths in older children. Reaching newborns requires skilled birth attendance and immediate postnatal care, which demand infrastructure investment that many health systems are still building.

Research published in The Lancet has noted that climate-related disruptions — droughts, floods, and displacement — are emerging as a growing threat to child health gains, particularly in regions where malnutrition and waterborne disease are already major risk factors. Sustaining the trend will require not just health system investment but a broader commitment to the conditions that keep children alive.

The record, for now, stands. And the work continues.
