The Contested Study Behind the USAID Cuts Death-Toll Fight, Explained A peer-reviewed Lancet study projecting more than 14 million deaths by 2030 from USAID cuts anchors a viral dispute, and its estimates swing widely with the modeling assumptions. Aaron Rafferty June 24, 2026 Key Takeaways A peer-reviewed Lancet study projects more than 14 million additional deaths by 2030 from USAID cuts, including about 4.5 million children under 5. The estimate is highly sensitive to assumptions, and other models put the toll far lower, from several hundred thousand to a few million. All the figures are modeled projections, not a verified death count, which is the core of the dispute. A contested death-toll estimate sits at the center of a viral fight over the USAID cuts. Representative Ro Khanna has cited a peer-reviewed study to argue the cuts could kill millions, while Elon Musk, who led the DOGE review that gutted the agency, calls the claim false and has threatened to sue. What the study actually says is more careful than either side's slogans. The study, published in The Lancet in July 2025 by a team at the Barcelona Institute for Global Health, evaluated two decades of USAID programs across 133 countries. It forecast that steep cuts could cause more than 14 million additional deaths by 2030, including about 4.5 million children under age 5, per France 24 and UCLA . That forecast is a projection, not a body count, and it rests on assumptions. The model compares a world where aid keeps flowing with one where the cuts hold through 2030, and it depends on how fast programs collapse and whether other donors fill the gap. Change those inputs and the number moves. A February 2026 follow-up from the same group projected 9.4 million deaths rather than 14 million, per CNN , and the
