Behind the Numbers: Why Global Progress on Saving Children’s Lives Has Ground to a Dangerous Crawl

GENEVA — An estimated 4.9 million children worldwide died before reaching their fifth birthday in 2024, according to a sweeping set of United Nations estimates released in March 2026. This includes 2.3 million newborns who perished within their first 28 days of life. While the historical data shows that under-five deaths have fallen by more than half since 2000, public health officials are sounding the alarm over a stark reality: global progress has drastically slowed, with the annual rate of decline dropping by more than 60 percent over the last decade.

The data, compiled by the United Nations Inter-agency Group for Child Mortality Estimation (UN IGME) and published as a series of five peer-reviewed research papers in The British Medical Journal (BMJ), reveals that the global momentum to eliminate preventable child deaths has hit a perilous plateau. Between 2000 and 2015, the global under-five mortality rate fell at an encouraging pace of 3.9 percent annually. However, between 2015 and 2024, that rate of decline slowed to a mere 1.5 percent.

A Slower Path to Survival

The global under-five mortality rate dropped to 37.4 deaths per 1,000 live births in 2024. While this represents progress from decades past, the mathematical reality means millions of children are slipping through the cracks of the global healthcare safety net.

The data highlights a critical bottleneck: neonatal deaths—those occurring within the first month of life—now account for 47 percent of all under-five fatalities. Delivering complex clinical care during the fragile neonatal period has proven much harder to scale than post-neonatal interventions like childhood vaccinations and oral rehydration therapies.

Global Under-Five Mortality Rate Decline:
2000–2015: 3.9% annual decline 
2015–2024: 1.5% annual decline ▬▬ (A 60%+ slowdown in progress)

“No child should die from diseases that we know how to prevent,” said UNICEF Executive Director Catherine Russell in a statement accompanying the data. “But we see worrying signs that progress in child survival is slowing – and at a time where we’re seeing further global budget cuts.”

Geographic Disparities: A Lottery of Birthplace

The burden of child mortality is not distributed equally. It is heavily concentrated in specific regions, turning basic survival into a lottery of where a child is born. In 2024, sub-Saharan Africa and Southern Asia combined to account for more than 80 percent of all under-five deaths, despite representing less than 60 percent of global live births.

A child born in sub-Saharan Africa faces an under-five mortality rate of 71.6 deaths per 1,000 live births—nearly 14 times higher than a child born in Europe or Northern America. Furthermore, infants in this region are 14 times more likely to die in their first month of life compared to newborns in Australia or New Zealand.

This divide deepens in fragile and conflict-affected nations. Geopolitical instability, damaged infrastructure, and displaced populations leave children in conflict zones nearly three times more likely to die before age five than those living in stable environments.

The Leading Killers Are Entirely Preventable

The tragedy of the UN IGME report lies in the causes of death. The vast majority of these children are dying from conditions that modern medicine mastered decades ago.

According to the data, the primary drivers of under-five mortality include:

• Preterm birth complications: Responsible for 36 percent of all neonatal deaths.

• Intrapartum-related events: Birth trauma or birth asphyxia (a lack of oxygen to the infant during labor), which accounts for 21 percent of neonatal deaths.

• Infectious diseases: Pneumonia, diarrhea, and neonatal sepsis remain major killers across all early childhood age brackets.

• Malaria: Accounts for 17 percent of under-five deaths globally and remains the single largest killer of young children in sub-Saharan Africa.

The Hidden Hand of Malnutrition

For the first time, the UN IGME report directly estimated deaths caused by severe acute malnutrition (SAM). The report found that more than 100,000 children aged 1 to 59 months died directly from SAM in 2024, with the highest tallies concentrated in Pakistan, Somalia, and Sudan.

However, researchers note that the true toll of malnutrition is vastly underestimated. When a child is chronically undernourished, their immune system degrades, leaving them highly vulnerable. A child suffering from malnutrition rarely has “malnutrition” written on their death certificate; instead, they die from common childhood infections like diarrhea or pneumonia because their bodies lack the strength to fight back.

The Macro Picture: Missing the SDG Targets

In 2015, the international community established the United Nations Sustainable Development Goals (SDGs). Target 3.2 called for all nations to reduce under-five mortality to 25 or fewer deaths per 1,000 live births by the year 2030.

The milestone data shows that while 134 countries have already achieved this target, and six more are on track to do so by 2030, a staggering 60 countries will fall short if current trends persist. These 60 lagging nations are home to roughly 42 percent (274.2 million) of the world’s under-five population. Public health models project that if the global community fails to accelerate its efforts, more than 27 million children will die between 2025 and 2030.

“These findings are a collective call to speed up implementation of the proven, scalable solutions we know are within reach,” noted Monique Vledder, World Bank Group Director for Health.

Data Gaps and Study Limitations

Independent epidemiologists point out that the numbers presented in the BMJ series represent best-guess statistical estimates rather than exact counts. In the parts of sub-Saharan Africa and Southern Asia where child mortality is highest, civil registration and vital statistics systems are frequently sparse or nonexistent.

Because researchers must rely on household surveys, structural censuses, and mathematical modeling, the uncertainty intervals for these regions are wide. Additionally, because local clinics frequently lack diagnostic tools, tracking the exact underlying cause of death—such as distinguishing between a death caused primarily by severe acute malnutrition versus one caused by an unmapped secondary infection—remains incredibly difficult.

The Path Forward: Low-Cost, High-Return Interventions

Reversing the slowdown does not require new scientific breakthroughs; it requires logistics, political will, and targeted funding.

Public health experts outline four critical pillars to jumpstart global progress:

1. Prioritize Local Health Financing: High-burden nations must establish domestic funding pipelines to insulate child survival programs from volatile international aid budgets.

2. Target High-Risk Zones: Resources must be intensely funneled into sub-Saharan Africa, Southern Asia, and active conflict zones.

3. Invest in Primary Healthcare Infrastructure: Building community health clinics allows families to access routine immunizations, prenatal checkups, and early diagnostic screening close to home.

4. Strengthen Data Accountability: Improving transparent, real-time data collection ensures health systems can spot localized disease outbreaks or nutritional crises before they escalate.

Evidence compiled by the World Bank shows that investing in early childhood survival remains one of the most cost-effective economic measures available. Every single dollar invested in basic child survival services can generate up to twenty dollars in long-term social and economic benefits.

“The science is clear,” concludes Li Liu, PhD, an associate professor at the Johns Hopkins Bloomberg School of Public Health and co-principal investigator of CA-CODE, who was not involved in compiling the core UN report. “Targeted investments in primary health care, maternal and newborn health services, routine immunization, nutrition programmes, and quality and timely data systems can save millions of lives.”
