These numbers matter—first, because of the dignity of those killed or still living.

Between May 6 and May 8, the UN’s Office for the Coordination of Humanitarian Affairs (OCHA) revised its estimates of how many women and children had died in Gaza. The numbers appeared to drop drastically: first, it reported at least 24,000 dead women and children, and two days later, it reported exactly 12,756 “identified” dead women and children. One could be forgiven for wondering whether the UN had raised about 6,700 Gazan children and 4,500 Gazan women from the dead.

OCHA has provided a running body count since the beginning of the Gaza war, and it currently stands at 34,844. This figure was generated by Hamas and is apparently accepted, give or take a few thousand, by Israelis. On a podcast last week, Israeli Prime Minister Benjamin Netanyahu estimated that Israel had killed roughly 14,000 combatants and said the country regretted the deaths of another 16,000 Palestinian civilians. The apparent downward revision was made without any accompanying statement to explain the change or sudden precision. Israel’s military did not make a big deal about it either, probably because there is no way to sound good when celebrating a reduction in the number of children you have killed.

Many noticed anyway. David Adesnik, a senior fellow at the Foundation for Defense of Democracies, gave the most detailed account of what had happened. For about two months, OCHA had been repeating numbers from Hamas’s Government Media Office, and on May 8 it switched back to Hamas’s Ministry of Health, its source at the beginning of the war. The Ministry of Health is acknowledged to be the more reliable of the two, and it is unclear why OCHA switched to the worse of the two sources, or switched back. A UN spokesperson, Farhan Haq, later explained that the Ministry of Health was “for whatever reason, given the conditions on the ground, unresponsive.” But the Ministry of Health kept publishing statistics in the interim. OCHA didn’t use them.
