Your median age is 18 due to all of your adults being murdered
This is a misrepresentation of the data.
So why are there so many children in Gaza? Demographers say it’s a combination of unusual factors. One is that an unusually low proportion of Palestinian women hold jobs. “It’s the place in the world where the least women work outside the home,” says Jon Pedersen of the Fafo Institute, a centre for demographic and social research in Oslo, Norway. Latest figures from the Palestinian Central Bureau of Statistics show that 14.7 per cent of women are in the labour market.
The data from Index Mundi show that the fertility rate in Gaza, 4.4 children per woman, is among the highest in the world. That has steadily fallen from a peak of 8.3 children per woman in 1991. This compares with a rate of 3 in Israel, although the overall rate there is elevated by higher rates of around 6 among the strictly orthodox Haredi Jews. In most European countries, it’s about 2. The second factor contributing to the high fertility rate is the fact that while women are housebound, their husbands earn more money as their families expand. “It’s employers that are willing to pay it,” says Pedersen. “Traditionally, men will get extra wages if they have extra children.”
“Whether the phenomenally high fertility levels in Gaza are also a more long-term response to political oppression and a perceived need to increase the numbers of Palestinians cannot be inferred from the data available, but it certainly seems to be a plausible hypothesis,” concludes Randall’s study. “In a situation where disempowerment, underemployment and marginalisation have left few opportunities for expression of identity, reproduction is one of the few liberties which remains, and also contributes to the larger goal of increasing the Palestinian people,” it says.
While the disempowerment of Palestinians may play a role in the equation, the high fertility rates are definitely a factor. Your argument was that adults are being killed off, and that’s simply not what the data presents.
