Demography Experts Criticize Gaza Death Toll Study for Serious Methodological Flaws

A recent study published in The Lancet Global Health estimated approximately 75,200 violent deaths in Gaza between October 2023 and January 2025, a figure more than 50% higher than Gaza's Ministry of Health estimates. This research, conducted by a team including members from Royal Holloway, University of London, has faced sharp criticism from demography experts who highlight significant methodological issues.

Critics point out that the study relied on unrepresentative samples, including data from areas with unusual household compositions and overlapping survey zones. The sampling methods were questioned, such as interviewing neighbors on a single street rather than conducting a comprehensive cross-sectional survey of the entire region. There are also concerns about potential duplicate death records and professional biases.

Professor Sergio Della Pergola, a demography and statistics expert from the Hebrew University, emphasized the problem of relying on "half-truths or false facts" in public discourse despite the tragic human loss. He noted that much of the data came from only two investigative teams, which appeared to focus on areas with particularly high victim concentrations, raising suspicion of bias. Della Pergola warned against the influence of anti-Israel bias within the academic community and called for maintaining professional standards amid emotionally and politically charged discussions.
