A groundbreaking study published in The Lancet has revealed what might be the tue devastating toll of the ongoing conflict in Gaza, estimating over 64,000 fatalities alone due to traumatic injuries just between October 7, 2023, and June 30, 2024. This figure far exceeds official reports and underscores the catastrophic impact of explosive violence on civilians.
The findings emerge from a capture–recapture analysis, a statistical method designed to account for underreporting, and highlights the severe challenges faced by health systems in conflict zones.
The research, led by Dr. Zeina Jamaluddine and colleagues, utilised three distinct data sources: Palestinian Ministry of Health (MoH) hospital records, an MoH online survey, and social media obituaries. By cross-referencing these lists and accounting for missing or unidentified records, the study concludes that the MoH’s reported death toll was underestimated by some 41%.
The report argues that the true scale of civilian suffering, however, may be even greater when factoring in deaths from non-traumatic causes.
A Public Health Crisis in Gaza
The annualised crude death rate from traumatic injuries during the study period was 39.3 per 1,000 people – 14 times higher than the all-cause mortality rate in Gaza in 2022. Women, children, and the elderly, according the Lancet, accounted for a significant portion of the deaths. Of the 28,257 fatalities with available demographic data, 59.1% were women, children under 18, or adults over 65.
The intensity of explosive violence, particularly during the initial months of the conflict, is evident in the monthly distribution of deaths. October, November, and December 2023 saw the highest numbers, coinciding with heavy aerial bombardments and ground operations in densely populated areas. The study estimates that over 34,000 fatalities went unrecorded in any official list, highlighting the immense difficulty in accurately documenting casualties amid active conflict.
The findings align with the global data trends from Action on Armed Violence (AOAV), whose 2024 Explosive Violence Monitor reported a huge increase in civilian harm in Gaza. AOAV’s analysis of explosive weapon use during the conflict identified widespread and indiscriminate attacks, with hospitals, schools, and residential areas frequently targeted. Such attacks disproportionately affected civilians, exacerbating the humanitarian crisis and placing immense strain on Gaza’s already fragile healthcare system.
Dr. Iain Overton, Executive Director of AOAV, said that “if at all accurate, this study paints a harrowing picture of the human cost of explosive violence in Gaza. The underreporting of deaths reflects the challenges of conflict zones, but it also calls into question the conduct of this military operation. We must demand accountability and an urgent focus on protecting civilian lives.”
The Methodology Behind the Numbers
The study’s capture–recapture method, initially developed for ecological studies, has been adapted for use in conflict zones to estimate mortality. By identifying overlaps and discrepancies across the three data sources, researchers could infer the number of unrecorded deaths. This approach, while robust, is not without limitations. Challenges in data cleaning and standardisation—such as variations in name spelling and missing demographic information—may have introduced some degree of bias. However, the consistency of findings across multiple statistical models lends a degree of credibility to the estimates and AOAV feels it offers another point on the arc of data on Gaza that causes contemplation.
The study also highlights the deteriorating quality of MoH data collection as the conflict progressed. Telecommunications blockades, attacks on healthcare facilities, and logistical disruptions hindered the documentation of deaths. Social media obituaries, while providing valuable supplementary data, were not immune to errors or omissions, particularly in verifying the identities of the deceased.
The implications of these findings extend far beyond the immediate conflict. Accurate mortality estimates are essential not only for documenting the human cost of war but also for informing international responses and shaping future conflict prevention strategies. The study’s authors emphasise the urgent need for expanded humanitarian access to Gaza, protection for healthcare workers, and efforts to rebuild the territory’s shattered health information systems.
Calls for Accountability
Dr. Overton said: “The international community must respond decisively to these findings. Civilians bear the brunt of explosive violence, and this cannot be ignored. Holding perpetrators accountable and ensuring compliance with international humanitarian law is not just a moral imperative – it’s a legal one.”
The study makes it clear that the broader public health consequences of the conflict need to be addresssed. Disruption to healthcare services, water and sanitation systems, and food supplies has likely contributed to a rise in deaths from non-traumatic causes. Previous projections by Jamaluddine and colleagues suggested significant increases in mortality from non-communicable diseases, infectious diseases, and maternal complications due to the conflict’s secondary effects.
The staggering mortality figures revealed by this study expose the devastating human cost of the Gaza conflict. Beyond the numbers lies an urgent need for action, Both to alleviate the ongoing humanitarian crisis and to address the systemic failures that allow such atrocities to persist.
