Answer

C

Explanation

The rate at which a population can be expected to grow in the future can be assessed graphically by means of a population pyramid-a bar graph displaying the number of people in each age category. Males are conventionally shown to the left of the vertical age axis and females to the right. A human population pyramid thus displays the age composition of a population by sex. In general, rectangular pyramids are characteristic of countries whose populations are stable, their numbers neither growing nor shrinking. A traingular pyramid is characteristic of a countrty that will exhibit rapid future growth, as most of its population has not yet entered the child-bearing years. Inverted traingles are characteristic of populations that are shrinking.
