Answer:

The population pyramid is a graphical depiction of age and sex structure of population in a certain region ( usually state).

Explanation:

Pyramid is not the most adequate term since it`s two-dimensional and has a shape of a triangle. Left side of this triangle represents males and the right side females. This pyramid is presented with a set of bars which are pilled one on another. The bars are longer on the base and shorter on the top, hence the shape of a triangle. Each bar represents a certain age range. The lowest bar represents the range from 0 to 4 years. The one above from 5 to 9 years, the next from 10 to 14 years and so on. The length of a bar represents the number or the percentage of that range in the given population.

The pyramid population is regarded as one of the best ways to visualize age structure in both sexes.
