I am just wondering what the graph would look like for BCD to be correct.

BC-If the population for all age groups are the same?
D-no way of knowing from this graph?

Let's say if the female side has less population in all ages compared to males (or vice versa) can this also cause an overall decrease in population or can that not be concluded.

B / C: yeah- all the population sizes for age groups would have to be the same.

D: If there's a huge amount of people going into the age of having babies.

Can you elaborate on that last part? For overall population size decreasing I just looked at all the oldies that are about to peace out.

D: what would be an age of having babies? 20-30? lols

And I meant something like this:

but applied to male or female.
My thoughts behind this is that reproduction needs both sexes, if one is more declined than the other, would the overall population decrease, or is that non concludable?

haha yeah, maybe even younger- basically whenever we are biologically able to which is puberty.

I guess the population is ultimately limited by females, so we could just check if there are more females in the older group than younger. This allows us to ignore the men side.
