World Population imbalance between the sexes

[kandrathe]

* There would be an increasing resource surplus from having to raise no new children for the first 18 years, followed by a slow shortage as we ran out of kids to enter the labour force, and lost productive capacity. Also, without new children we would have to subtract infant mortality and deaths in childbirth, which should lower the mortality rate.

I think the shortages due to excessive numbers of elderly is a bit over blown. I believe we will just see shifts in the burden across age demographics. Youth will be in higher demand, but the elderly will fill in where help is needed. These studies do not account for the quality of life changes, and that many of these elderly are fully capable to continuing to be productive well past 70 years old. If given the choice of working or starvation, the result will be more elderly (60 to 80 years old) will continue in the work force. Also, this trend has happened before, during the world wars when we sent off large numbers of healthy young men to be slaughtered on the battlefields.
