The fragile progress made in reducing child mortality over the past two decades is now at risk of unraveling. A new report by a United Nations inter-agency group has issued a stark warning: if current trends continue, an estimated 27.3 million children will die before their fifth birthday by 2030, most from preventable causes. The findings point to a troubling slowdown in global efforts to save young lives, driven by a convergence of crises ranging from climate change to armed conflict and declining international funding.
In 2024 alone, the most recent year with consolidated data, approximately 4.9 million children under the age of five died worldwide. Nearly half of these deaths—2.3 million—occurred within the first 28 days of life, highlighting the extreme vulnerability of newborns. The burden is not evenly distributed. Sub-Saharan Africa and South Asia account for roughly 80 percent of all child deaths, with projections indicating that these regions will continue to bear the heaviest toll in the coming years.
Between 2000 and 2015, the world witnessed remarkable progress in reducing child mortality, fueled by large-scale investments in maternal and child health. Vaccination campaigns, improved access to healthcare, and targeted interventions helped save millions of lives. However, since 2015, the pace of improvement has slowed dramatically—by more than 60 percent, according to the report. Experts attribute this stagnation to shifting investment priorities, reduced development assistance, and a growing number of global emergencies.
The challenges facing child survival today are more complex and interconnected than ever before. Climate-related disasters are increasing in frequency and intensity, displacing communities and straining already fragile health systems. Conflicts continue to devastate infrastructure and limit access to basic services. Economic instability further compounds these issues, leaving millions of families unable to access essential care for their children.
Healthcare systems in many high-burden countries remain under-resourced and overstretched. In remote or conflict-affected areas, reaching vulnerable populations is particularly difficult. Shortages of trained health workers, limited medical supplies, and inadequate infrastructure all contribute to preventable deaths. Essential treatments—such as antibiotics for pneumonia, antimalarial drugs, and therapies for HIV—are often unavailable to those who need them most.
The situation is further exacerbated by declining global health funding. Experts warn that recent budget cuts could have devastating consequences. Historical evidence suggests that when international aid is reduced, child mortality rates can increase by three to four percent annually. Some projections estimate that funding cuts could result in an additional 1.2 million to 4.5 million deaths of children under five by 2030. While the exact figures vary depending on methodology, the overarching message is clear: reduced investment puts lives at risk.
Newborns remain the most vulnerable group. Complications related to premature birth account for 36 percent of neonatal deaths, followed by complications during labor and delivery at 21 percent. Infections such as neonatal sepsis and congenital anomalies also contribute significantly. Preventing these deaths often requires relatively simple interventions, including skilled birth attendance, access to clean facilities, and timely medical care—resources that are still lacking in many parts of the world.
After the first month of life, infectious diseases become the leading causes of death. Malaria alone accounts for 17 percent of deaths among children aged one month to five years, with the majority occurring in sub-Saharan Africa. Pneumonia and diarrhea also remain major killers, despite being largely preventable and treatable. These diseases thrive in environments where poverty, malnutrition, and inadequate sanitation persist.
For the first time, the report provides estimates of deaths directly caused by severe acute malnutrition, which claimed more than 100,000 young lives in 2024. However, experts caution that this figure likely underrepresents the true impact. Malnutrition weakens the immune system, making children more susceptible to other deadly illnesses. As a result, it often goes unrecorded as an underlying cause of death, masking its full contribution to child mortality.
Africa remains the epicenter of the crisis, accounting for 58 percent of all deaths among children under five. In countries such as Nigeria, Niger, and Somalia, mortality rates still exceed 100 deaths per 1,000 live births. Nearly half of these deaths occur within the first month of life, often due to preventable complications. Beyond the neonatal period, infectious diseases and malnutrition dominate.
Fragility and conflict play a significant role in shaping these outcomes. In sub-Saharan Africa, 19 countries classified as fragile or conflict-affected account for 73 percent of child deaths in the region. Children in these settings face heightened risks due to displacement, food insecurity, and the breakdown of healthcare systems. Even in the absence of conflict, systemic weaknesses—such as uneven distribution of health workers and limited access to clean water and sanitation—continue to endanger lives.
Despite these challenges, the report highlights examples of progress that demonstrate what is possible with sustained commitment. Sierra Leone, for instance, has reduced its under-five mortality rate by 65 percent since 1990. Burkina Faso has achieved a 26 percent reduction since 2015, even while grappling with humanitarian crises and climate shocks. These cases underscore the potential for improvement when targeted interventions are implemented effectively.
Beyond early childhood, the report also sheds light on mortality among older children and young people. In 2024, approximately 2.1 million individuals aged 5 to 24 died worldwide. Among younger children, infectious diseases and injuries remain leading causes of death. In adolescence, the risks shift significantly: self-harm emerges as the leading cause of death among those aged 15 to 19, while road traffic accidents disproportionately affect teenage boys.
The findings paint a sobering picture of a world at a crossroads. Decades of progress in child survival are under threat, and the consequences of inaction could be devastating. Yet the report also emphasizes that most of these deaths are preventable. Proven solutions exist, from basic healthcare interventions to broader efforts addressing poverty, education, and infrastructure.
What is needed now is renewed global commitment. Without urgent and coordinated action, millions of children will continue to die unnecessarily, their lives cut short by conditions the world has the knowledge and tools to overcome.
