Work Step by Step
A population with an age distribution shaped like a pyramid typically exhibits a high crude birth rate (III) because it has a large proportion of young individuals capable of reproductive age.
It is also likely to exhibit a high population momentum (II) because of the large number of young individuals entering the reproductive age, leading to continued population growth despite declining birth rates.
However, it does not necessarily exhibit a stable population size (I), as its high birth rate and momentum can result in continued population growth.
The answer is (e).
