What is a population pyramid?
What will be an ideal response?
Answer: A population pyramid is a bar graph that displays a country's population by age and gender. The shape of a country's pyramid is determined primarily by the crude birth rate (CBR). A country with a high CBR has a relatively large number of young children, making the base of the pyramid very broad, whereas a country with a relatively large number of older people has a graph with a wider top that looks more like a rectangle than a pyramid. As a country advances and moves through the different stages of the demographic transition model, therefore, its population pyramid narrows at the base and, compared to previous stages, the upper part of the pyramid widens, changing the pyramid from a more "triangular" shape to a more "rectangular" one.
