The current death toll in Gaza is close to 42,000, but experts believe that figure is likely a gross undercount.

      If we assume that (1) the civilian population is 50% children and (2) none of the combatants are children then:

      (fraction of the dead that is children) = (fraction of the dead that is civilians) * (fraction of the civilians that is children)

      (1/3) = (fraction of the dead that is civilians) * (1/2)

      (fraction of the dead that is civilians) = (1/3) ÷ (1/2) = (2/3)

      This is where my 2:1 civilians to combatants number comes from.

      The fact that among the dead, the ratio of civilians to combatants equals the ratio of adults to children is a coincidence.

        The amount “civilians” in your calculations is tricky. The first time it appears it refers to dead civilians, the second time it appears to the overall civilian population (hence the 1/2 using the rule of thumb that half of Gazans are under 18).

        I.e you can’t say

        #deadKids/#allDead = #deadCivilians/#allDead * #deadKids/#allCivilians

        Because #deadCivilians << #allCivilians

          That’s not what I’m saying - I don’t have a term that represents “#deadKids/#allCivilians”.

          If I were to use your notation, I would write:

          #deadKids/#allDead = #deadCivilians/#allDead * #allKids/#allCivilians

          I recognize that it’s macabre to treat this as a word problem, but the math works out if you do. If out of 100 dead people, 33 are combatants and 67 are civilians (the 2:1 civilian to combatant ratio I have calculated) and half of the dead civilians are children, then there are 33 dead children, which is the “one third” in the headline.

            I thought originally that you were suggesting a simple syntactic manipulation of the fraction but you’re not. I don’t understand why the equation you propose is reasonable.

              Let me try to explain it another way.

              We know that 1/3 of the dead are children, according to the headline. We also know that children make up about half the population of Gaza. We assume that none of the combatants are children.

              If a person is killed, that person is either an adult combatant, an adult civilian, or a child civilian. Since child civilians make up 1/3 of the dead and there are as many adult civilians as child civilians in Gaza, adult civilians therefore make up another 1/3 of the dead. That adds up to 2/3 of the dead being civilians. 2/3 civilian dead and 1/3 combatant dead is a 2:1 ratio of civilians to combatants killed.
