Could not find a chart with the breakdown "of them children" for Palestine on Statista.

Experts believe the real death toll in Gaza is at least ~4.4x what this shows, so IOF is more accurately ~40 times worse.

Applying a conservative estimate of four indirect deaths per one direct death to the 37,396 deaths reported, it is not implausible to estimate that up to 186,000 or even more deaths could be attributable to the current conflict in Gaza.

Using this estimate, the civilian deaths per day average is 497.33 in Gaza.

The UN agency said it verified the details of 8,119 people killed in Gaza from November 2023 to April 2024.

Its analysis found around 44% of verified victims were children and 26% women. The ages most represented among the dead were five to nine-year-olds.

About 80% of victims were killed in residential buildings or similar housing, the agency added.
