A study finds Gaza war deaths are 41% higher than reported, using capture-recapture analysis to highlight healthcare impact.

LONDON (Reuters) - An official Palestinian tally of direct deaths in the Israel-Hamas war likely undercounted the number of casualties by 41% through the middle of 2024 as the Gaza Strip's healthcare infrastructure unravelled, according to a study published on Thursday.
The peer-reviewed statistical analysis published in The Lancet journal was conducted by academics at the London School of Hygiene and Tropical Medicine, Yale University and other institutions.
Using a statistical method called capture-recapture analysis, the researchers sought to assess the death toll from Israel's air and ground campaign in Gaza in the first nine months of the war, between October 2023 and the end of June 2024.
They estimated 64,260 deaths due to traumatic injury during this period, about 41% higher than the official Palestinian Health Ministry count. The study said 59.1% were women, children and people over the age of 65. It did not provide an estimate of Palestinian combatants among the dead.
More than 46,000 people have been killed in the Gaza war, according to Palestinian health officials.
The war began on Oct. 7, after Hamas gunmen stormed across the border with Israel, killing 1,200 people and taking more than 250 hostages, according to Israeli tallies.
The Lancet study said the Palestinian health ministry's capacity for maintaining electronic death records had previously proven reliable, but deteriorated under Israel's military campaign, which has included raids on hospitals and other healthcare facilities and disruptions to digital communications.
Israel says it goes to great lengths to avoid civilians deaths and accuses Hamas of using hospitals as cover for its operations, which the militant group denies.
STUDY METHOD EMPLOYED IN OTHER CONFLICTS
Anecdotal reports suggested that a significant number of dead remained buried in the rubble of destroyed buildings and were therefore not included in some tallies.
To better account for such gaps, the Lancet study employed a method used to evaluate deaths in other conflict zones, including Kosovo and Sudan.
Using data from at least two independent sources, researchers look for individuals who appear on multiple lists of those killed. Less overlap between lists suggests more deaths have gone unrecorded, information that can be used to estimate the full number of deaths.
For the Gaza study, researchers compared the official Palestinian Health Ministry death count, which in the first months of war was based entirely on bodies that arrived in hospitals but later came to include other methods; an online survey distributed by the health ministry to Palestinians inside and outside the Gaza Strip, who were asked to provide data on Palestinian ID numbers, names, age at death, sex, location of death, and reporting source; and obituaries posted on social media.
"Our research reveals a stark reality: the true scale of traumatic injury deaths in Gaza is higher than reported," lead author Zeina Jamaluddine told Reuters.
