The most comprehensive accounting of the Gaza humanitarian crisis — compiled by the United Nations, the World Bank, and the European Union — puts the total cost of the war at $57.9 billion in direct damage and economic losses, with long-term reconstruction needs estimated at $71.4 billion. More than 72,600 Palestinians have been killed since October 7, 2023, over 1.9 million people have been displaced, and Gaza now holds the grim distinction of having the highest number of child amputees per capita anywhere in the world.
A Population Nearly Entirely Displaced
Of Gaza’s roughly 2.3 million residents, 1.9 million — approximately 85% — have been internally displaced since the conflict escalated. Many have been forced to relocate not once but multiple times, cycling through overcrowded emergency shelters and tent camps with collapsing sanitation infrastructure. In southern Gaza, a single infrastructure failure recently cut off reliable access to clean drinking water for 500,000 people. Cooking gas shortages have become so severe that nearly half the population has resorted to burning waste for fuel.
The death toll breaks down in ways that are hard to sit with. Of the more than 72,600 Palestinians reported killed, child fatalities exceed 21,200. Over 171,000 have been injured. Thousands of additional bodies remain buried under the rubble of collapsed buildings, still unrecovered. In the West Bank — separate from Gaza — more than 1,160 Palestinians have been killed in Israeli military operations, and 45 Palestinian communities have been displaced since early 2023, nine of them in the first months of 2026 alone. International monitors recorded an average of six settler attacks per day in 2026. On the Israeli side, the October 7, 2023 attacks killed 1,195 people, including 815 civilians and 36 children, with cumulative Israeli fatalities across the broader conflict reaching approximately 2,039.
The Infrastructure That Sustained Life Is Gone
The Rapid Damage and Needs Assessment published by international bodies puts direct physical damage to Gaza’s infrastructure at $35.2 billion. Housing absorbed 51% of that — $18 billion in residential destruction, with entire neighborhoods erased. Commercial spaces, factories, and markets lost another $6.35 billion. Road networks and transit infrastructure: $3.2 billion. Water, sanitation, and hygiene systems — the literal pipelines of survival — suffered $1.7 billion in damage to desalination plants and water networks.
The health system has effectively collapsed. Combined damages and economic losses to the health sector reach $8.2 billion, and as of mid-2026, less than 43% of Gaza’s 683 health service points are even partially operational. Only 23 facilities are fully functioning. Pregnant women, the chronically ill, and trauma patients — the people who need a hospital the most — are operating in a system that can no longer hold them. At least 593 aid workers have been killed since the war began, making this one of the deadliest operating environments for humanitarian personnel in recorded history. Much like what happened with the displacement crises that reshaped Latin America, the compounding effect of losing healthcare alongside housing and food security creates generational damage that outlasts the conflict itself.
Education has not been spared. Total losses to the sector sit at $3.4 billion. At least 792 teachers and school personnel have been killed. The consequence: more than 728,000 school-aged children have been completely out of formal schooling for over two consecutive years. That is not a disruption. That is a lost generation of basic education, compounded by trauma, displacement, and the psychological weight of growing up in an active war zone.
What Rebuilding Would Actually Cost
International financial institutions estimate the total long-term reconstruction needs for Gaza at $71.4 billion — a figure that accounts for clearing millions of tons of hazardous rubble, rebuilding a near-total collapse of GDP, and recovering $2.8 billion in labor losses from the near-elimination of employment. The combined direct damage and ongoing economic losses already total $57.9 billion. These are not abstract projections. They represent what it would take to return Gaza to a functional baseline — not prosperity, not growth, just the ability to sustain a population that has spent almost three years losing everything. The ceasefire reached in late 2025 paused active bombardment, but it has not stopped the slow erosion of every system that makes ordinary life possible. The data is in. The question of who pays for reconstruction — and whether the political will exists to actually do it — is the one no report can answer.
