kiruha [24]

Answer:

A. a developing nation

The overall shape of an age pyramid indicates if the population is increasing, stationary, or shrinking.

The age structure diagram for a developing nation has a broad base that tapers quickly towards the top. This means that a larger percentage of the population is in the pre-reproductive age group and reproductive age group with a smaller percentage of the population in the post-reproductive age. These countries have a great chance of future population growth.
