I don't know if you've come across these before, but anyway, a population pyramid is a way of visualising the spread of ages of the population of a country. Also the sex.
It is interesting that there is now, what has been referred to as, a youth bulge in many middle eastern countries. Normally you would expect that at the bottom of the pyramid would be many small children, this amount decreasing as the pyramid rose and the age increased.
However, this is not always so. In Algeria there is a clear bulge in the 20 - 35 age group, same in Morocco. This is even exaggerated in Tunisia, less so in Libya, more so in Iran.
There seems to be a clear trend that in the middle east the populations are 'overpopulated' by those in their 20's.
Check out European countries.
Notice the difference?
Now look at the poorer African countries.
Hmmm, interesting.
To throw a bit of an anomaly into the ring - look at Saudi Arabia, and then UAE.
So - click on the link, click on 'submit' first to bring up several tabs, click on the tab for 'population pyramids' if it's not defaulted to it. Select 2011 and the country and then 'submit'.
(You can check back a bit in the years but the permutations are endless)
