Without getting into the debate about whether or not what is happening is a "genocide" or not, your data proves nothing since it cuts off before the events in questions started. Why not post an updated graph and include the number up through end of September 2024 so that it would at least be a relevant data point to the discussion?
Even the most pessimistic estimates of casualties in Gaza are on the order of tens of thousands. That is not going to appreciably change the population.
So why did you even post that graph if it has nothing to do with anything?
